15 years agoshrink struct dentry
Nick Piggin [Mon, 1 Dec 2008 08:33:43 +0000 (09:33 +0100)]
shrink struct dentry

struct dentry is one of the most critical structures in the kernel. So it's
sad to see it going neglected.

With CONFIG_PROFILING turned on (which is probably the common case at least
for distros and kernel developers), sizeof(struct dcache) == 208 here
(64-bit). This gives 19 objects per slab.

I packed d_mounted into a hole, and took another 4 bytes off the inline
name length to take the padding out from the end of the structure. This
shinks it to 200 bytes. I could have gone the other way and increased the
length to 40, but I'm aiming for a magic number, read on...

I then got rid of the d_cookie pointer. This shrinks it to 192 bytes. Rant:
why was this ever a good idea? The cookie system should increase its hash
size or use a tree or something if lookups are a problem. Also the "fast
dcookie lookups" in oprofile should be moved into the dcookie code -- how
can oprofile possibly care about the dcookie_mutex? It gets dropped after
get_dcookie() returns so it can't be providing any sort of protection.

At 192 bytes, 21 objects fit into a 4K page, saving about 3MB on my system
with ~140 000 entries allocated. 192 is also a multiple of 64, so we get
nice cacheline alignment on 64 and 32 byte line systems -- any given dentry
will now require 3 cachelines to touch all fields wheras previously it
would require 4.

I know the inline name size was chosen quite carefully, however with the
reduction in cacheline footprint, it should actually be just about as fast
to do a name lookup for a 36 character name as it was before the patch (and
faster for other sizes). The memory footprint savings for names which are
<= 32 or > 36 bytes long should more than make up for the memory cost for
33-36 byte names.

Performance is a feature...

V4L/DVB (10129): dvb: remove deprecated use of RW_LOCK_UNLOCKED in frontends

Impact: clean up

RW_LOCK_UNLOCKED is deprecated.  This patch replaces it with the
__RW_LOCK_UNLOCKED(lock) macro.  This change was a little trickier than
others due to the macro being used in another macro that fills an array.

V4L/DVB (10119): em28xx: fix corrupted XCLK value

Correct problem introduced during the board refactoring where the XCLK
frequency would get zero'd out.  The sequence of events was as follows:

em28xx_pre_card_setup() called em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration
em28xx_pre_card_setup() would set the dev->board.xclk if not set
em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk
...
em28xx_card_setup() would call em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration (clearing out
 value of dev->board.xclk set in em28xx_pre_card_setup)
...
em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk
 (which now contains zero)

The change sets the default XCLK and I2C Clock fields in the board definition
inside of em28xx_set_model() so that subsequent calls do not cause the
values to be overwritten.
