ocfs2: constify attribute_group structures

attribute_groups are not supposed to change at runtime.  All functions
working with attribute_groups provided by <linux/sysfs.h> work with
const attribute_group.  So mark the non-const structs as const.

7 years agocompiler, clang: always inline when CONFIG_OPTIMIZE_INLINING is disabled
David Rientjes [Thu, 6 Jul 2017 22:35:24 +0000 (15:35 -0700)]
compiler, clang: always inline when CONFIG_OPTIMIZE_INLINING is disabled

The motivation for commit abb2ea7dfd82 ("compiler, clang: suppress
warning for unused static inline functions") was to suppress clang's
warnings about unused static inline functions.

For configs without CONFIG_OPTIMIZE_INLINING enabled, such as any non-x86
architecture, `inline' in the kernel implies that
__attribute__((always_inline)) is used.

Some code depends on that behavior, see
  https://lkml.org/lkml/2017/6/13/918:

  net/built-in.o: In function `__xchg_mb':
  arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99'
  arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99

The full fix would be to identify these breakages and annotate the
functions with __always_inline instead of `inline'.  But since we are
late in the 4.12-rc cycle, simply carry forward the forced inlining
behavior and work toward moving arm64, and other architectures, toward
CONFIG_OPTIMIZE_INLINING behavior.

 "A big break-through came during this development cycle as a way was
  found to maintain the existing umount -l semantics while allowing for
  optimizations that improve the performance. That is represented by the
  first change in this series moving the reparenting of mounts into
  their own pass. This has allowed addressing the horrific performance
  of umount -l on a carefully crafted tree of mounts with locks held
  (0.06s vs 60s in my testing). What allowed this was not changing where
  umounts propagate to while propgating umounts.

  The next change fixes the case where the order of the mount whose
  umount are being progated visits a tree where the mounts are stacked
  upon each other in another order. This is weird but not hard to

   - Andreas Gruenbacher has four patches related to cleaning up the
     GFS2 inode evict process. This is about half of his patches
     designed to fix a long-standing GFS2 hang related to the inode
     shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
     memory and blocks on the shrinker.

     These four patches have been well tested. His second set of patches
     are still being tested, so I plan to hold them until the next merge
     window, after we have more weeks of testing. The first patch
     eliminates the flush_delayed_work, which can block.

   - Andreas's second patch protects setting of gl_object for rgrps with
     a spin_lock to prevent proven races.

   - His third patch introduces a centralized mechanism for queueing
     glock work with better reference counting, to prevent more races.

    -His fourth patch retains a reference to inode glocks when an error
     occurs while creating an inode. This keeps the subsequent evict
     from needing to reacquire the glock, which might call into DLM and
     block in low memory conditions.

   - Arvind Yadav has a patch to add const to attribute_group
     structures.

   - I have a patch to detect directory entry inconsistencies and
     withdraw the file system if any are found. Better that than silent
     corruption.

   - I have a patch to remove a vestigial variable from glock

Cavium CNN55XX: fix broken default Kconfig entry

Every developer always thinks that _their_ code is so special and
magical that it should be enabled by default.

And most of them are completely and utterly wrong.  That's definitely
the case when you write a specialty driver for a very unsual "security
processor". It does *not* get to mark itself as "default m".

If you solve world hunger, and make a driver that cures people of
cancer, by all means enable it by default.  But afaik, the Cavium
CNN55XX does neither.

   There's also now genfscon labeling support for tracefs, which was
   lost in v4.1 with the separation from debugfs.

 - Smack incorporates a safer socket check in file_receive, and adds a

nfp: default to chained metadata prepend format

ABI 4.x introduced the chained metadata format and made it the
only one possible.  There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath.  In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities.  The default was left to non-chained.

In case of fallback traffic, there is no capability telling the
driver there may be chained metadata.  With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.

This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway.  New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

nfp: improve order of interfaces in breakout mode

For historical reasons we enumerate the vNICs in order.  This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.

What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.

Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:

pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2

   - STM32 gains support for three new boards: stm32h743-disco,
     stm32f746-disco, and stm32f769-disco, along with new device support
     for the existing stm32f429 boards.

   - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H with
     10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module plus
     board.

   - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
     wireless router.

   - For NXP i.MX, we gain support for the Gateworks Ventana GW5600 and
     the Technexion Pico i.MX7D single-board computers.

   - The BeagleBone Blue is added for OMAP, it's the latest variation of
     the popular Beaglebone Black single-board computer.

   - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards are
     added, these are the latest variations of a seemingly endless
     supply of similar single-board computers.

  Other updates:

   - Linus Walleij improves support for the "Faraday" based SoC
     platforms from various SoC makers (Moxart, Aspeed, Gemini)

   - The ARM Mali GPU is now describe on Rockchips SoCs

   - Mediatek MT7623 is extended significantly, making it much more
     useful.

   - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
     Allwinner, Qualcomm, iMX

   - For Amlogic, the clock support is extended a lot on meson8b.

   - We now build the devicetree file for the Raspberry Pi 3 on 32-bit

Merge branch 'net-subsystem-misc-refcounter-conversions'

Elena Reshetova says:

====================
v2 net subsystem misc refcounter conversions

Changes in v2:
 * rebase on top of net-next
 * currently by default refcount_t = atomic_t (*) and uses all
   atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled.
   This is a compromise for the systems that are critical on
   performance (such as net) and cannot accept even slight delay
   on the refcounter operations.

This series, for various misc network components, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
These are the last networking-related conversions with the exception of
network drivers (to be send separately).

Please excuse the long patch set, but seems like breaking it up
won't save that much on CC list and most of the changes are
trivial.

The patches are fully independent and can be cherry-picked separately.
In order to try with refcount functionality enabled in run-time,
CONFIG_REFCOUNT_FULL must be enabled.

NOTE: automatic kernel builder for some reason doesn't like all my
network branches and regularly times out the builds on these branches.
Suggestion for "waiting a day for a good coverage" doesn't work, as
we have seen with generic network conversions. So please wait for the
full report from kernel test rebot before merging further up.
This has been compile-tested in 116 configs, but 71 timed out (including
all s390-related configs again). I am trying to see if they can fix
build coverage for me in meanwhile.

* The respective change is currently merged into -next as
  "locking/refcount: Create unchecked atomic_t implementation".
