This commit is a part of preparation to perform allocation/release

At present, several operations are done in pcm.prepare callback. To

set sampling transfer frequency in pcm.hw_params callback.

the initrd even if it doesn't exist.

In the non-existent case this causes a boot-time splat if
CONFIG_DEBUG_VIRTUAL is enabled due to a call to virt_to_phys() with a

Instead we should check that the initrd actually exists and only attempt

There is no reproducer and it is difficult to hit -- 1 crash every few
days.  The issue is very similar to the fix in commit 6b0868c820ff
("mm/compaction.c: correct zone boundary handling when resetting pageblock
skip hints").  When isolating free pages around a target pageblock, the
boundary handling is off by one and can stray into the next pageblock.
Triggering the syzbot error requires that the end of pageblock is section
or zone aligned, and that the next section is unpopulated.

A more subtle consequence of the bug is that pageblocks were being
improperly used as migration targets which potentially hurts fragmentation
avoidance in the long-term one page at a time.

A debugging patch revealed that it's definitely possible to stray outside
of a pageblock which is not intended.  While syzbot cannot be used to
verify this patch, it was confirmed that the debugging warning no longer
triggers with this patch applied.  It has also been confirmed that the THP
allocation stress tests are not degraded by this patch.

5 years agomm/vmap: add DEBUG_AUGMENT_LOWEST_MATCH_CHECK macro
Uladzislau Rezki (Sony) [Fri, 17 May 2019 21:31:37 +0000 (14:31 -0700)]
mm/vmap: add DEBUG_AUGMENT_LOWEST_MATCH_CHECK macro

This macro adds some debug code to check that vmap allocations are
happened in ascending order.

By default this option is set to 0 and not active.  It requires
recompilation of the kernel to activate it.  Set to 1, compile the
kernel.
