When you put
.section ".foo"
in an assembly file instead of
.section "foo", "ax"
, one of the possible symptoms is that modpost will see an
ld-generated section name ".foo.1" in section_rel() or section_rela().
But this heuristic has two problems: it will miss a bad section that
has no relocations, and it will incorrectly flag many gcc-generated
sections as bad when compiling with -ffunction-sections
-fdata-sections.
On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one:
WARNING: crypto/cryptd.o (.text.T.349): unexpected section name.
So instead of checking whether the section name matches a particular
pattern, we directly check for a missing SHF_ALLOC in the section
flags.

While building the kernel, we end-up calling modpost with -K and -M
options for the same file (Modules.markers). This is resulting in
modpost's main function calling read_markers() and then write_markers() on
the same file.
We then have read_markers() mmap'ing the file, and writer_markers()
opening that same file for writing.
The issue is that read_markers() exits without munmap'ing the file and is
as a matter holding a reference on Modules.markers. When write_markers()
is opening that very same file for writing, we still have a reference on
it and cygwin (Windows?) is then making fopen() fail with EPERM.
Calling release_file() before exiting read_markers() clears that reference
(and memory leak) and fopen() then succeeds.
Tested on both cygwin (1.3.22) and Linux. Also ran modpost within
valgrind on Linux to make sure that the munmap'ed file was not accessed
after read_markers()

Oprofile is changing the naming it is using for the compatibility modes.
Instead of having compat-power<x>, oprofile will go to family naming

The ocfs2 directory index updates two blocks when we remove an entry -

accounting for the dx leaf. This shows up when ocfs2_delete_inode()
runs out of credits in jbd2_journal_dirty_metadata() at
"J_ASSERT_JH(jh, handle->h_buffer_credits > 0);".
The test that caught this was running dirop_file_racer from the

blocksize, it forces the orphan dir index to grow large enough to
trigger.

According to the gettimeofday(2) manual:
If either tv or tz is NULL, the corresponding structure is not
set or returned.
Since it is legal to give NULL as the tv argument, the code should make
sure tv is not NULL before trying to dereference it.
This issue manifests itself on x86_64 when vdso=0 is not on the kernel
command-line and libc uses the vDSO for gettimeofday() (e.g. glibc >=
2.7). A simple reproducer:
#include <stdio.h>
#include <sys/time.h>
int main(void)
{
struct timezone tz;
gettimeofday(NULL, &tz);
return 0;
}

xfs_getbmap (or rather the formatters called by it) copy out the getbmap
structures under the ilock, which can deadlock against mmap. This has
been reported via bugzilla a while ago (#717) and has recently also
shown up via lockdep.
So allocate a temporary buffer to format the kernel getbmap structures
into and then copy them out after dropping the locks.
A little problem with this is that we limit the number of extents we
can copy out by the maximum allocation size, but I see no real way
around that.

the extext list. While xfs_bmap_last_offset() is trying to lookup
what was the last extent some extents were merged and the extent list
shrunk so the index we lookup is now beyond the end of the extent list
and potentially in a freed buffer.

eCryptfs: Fix min function comparison warning
ecryptfs: fix printk format warning
On several mv643xx_eth hardware versions, the two 64bit mib counters
for 'good octets received' and 'good octets sent' are actually 32bit
counters, and reading from the upper half of the register has the same
effect as reading from the lower half of the register: an atomic
read-and-clear of the entire 32bit counter value. This can under heavy
traffic occasionally lead to small numbers being added to the upper
half of the 64bit mib counter even though no 32bit wrap has occured.
Since we poll the mib counters at least every 30 seconds anyway, we
might as well just skip the reads of the upper halves of the hardware
counters without breaking the stats, which this patch does.

Currently, when OOM occurs during rx ring refill, mv643xx_eth will get
into an infinite loop, due to the refill function setting the OOM bit
but not clearing the 'rx refill needed' bit for this queue, while the
calling function (the NAPI poll handler) will call the refill function
in a loop until the 'rx refill needed' bit goes off, without checking
the OOM bit.
This patch fixes this by checking the OOM bit in the NAPI poll handler
before attempting to do rx refill. This means that once OOM occurs,
we won't try to do any memory allocations again until the next invocation
of the poll handler.
While we're at it, change the OOM flag to be a single bit instead of
one bit per receive queue since OOM is a system state rather than a
per-queue state, and cancel the OOM timer on entry to the NAPI poll
handler if it's running to prevent it from firing when we've already
come out of OOM.

Currently drivers/media drivers are linked very early - directly after
base, block, misc, and mfd and before ata, scsi, ide, input, firewire,
usb, and i2c. This breaks static build of video4linux drivers, that use
generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because
during video4linux probing the v4l2-subdev core requires a struct
i2c_adapter context, which cannot be satisfied before the i2c subsystem is
initialised. Moving drivers/media after drivers/i2c fixes this problem.
The best way to trigger action is by submitting a patch:-) So, let's see
what comes out of it - on the one hand I don't see any reason why media
has to be linked this early, and nobody was able to give me one yesterday
as this problem has been discussed on linux-media, OTOH, maybe indeed it
would be better to move i2c the whole way up above media, but that'd be
much bigger of a change, I think.
