io_submit_one assigns ki_left = ki_nbytes = iocb->aio_nbytes, then calls
down to aio_setup_iocb, then to aio_setup_single_vector. In there,
ki_nbytes is reassigned to the same value it got two call stack above it.
There is no need to do so.

Heh, the very first line:
fs/exec.c(1465): remark #593: variable "flag" was set but never used
fs/exec.c:
1477 /*
1478 * We cannot trust fsuid as being the "true" uid of the
1479 * process nor do we know its entire history. We only know it
1480 * was tainted so we dump it as root in mode 2.

1482 if (mm->dumpable == 2) { /* Setuid core dump mode */
1483 flag = O_EXCL; /* Stop rewrite attacks */
1484 current->fsuid = 0; /* Dump root private */
1485 }
And then filp_open follows with "flag" totally ignored.
(akpm: this restores the code to Alan's original version. Andi's "Support
piping into commands in /proc/sys/kernel/core_pattern" (cset d025c9db) broke
it).

Twenty characters in cp936 are not correctly handled. They're all in the
U00 plane. nls_cp936 converts all U00XY to XY but this is not correct for
some characters.(e.g. U00B7 -> A1A4, U00A8 -> A1A7).
This problem is fixed by generating u2c_00 based on all c2u_xx and changing
uni2char() to give U00 plane a special handling. The "â¬"(U20AC,80 in
cp936) is also be handled properly.

This patch removes the unused NFSD_OPTIMIZE_SPACE.
Additionally, it does differently what NFSD_OPTIMIZE_SPACE was supposed to do:
Nowadays, gcc knows best when to inline code, and CONFIG_CC_OPTIMIZE_FOR_SIZE
even tells gcc globally whether to optimize for size or for speed. Therefore,
this patch also removes all inline's from these files.

If you do something like:
# touch foo
# tail -f foo &
# rm foo
# <take snapshot>
# <mount snapshot>
you'll panic, because ext3/4 tries to do orphan list processing on the
readonly snapshot device, and:
kernel: journal commit I/O error
kernel: Assertion failure in journal_flush_Rsmp_e2f189ce() at journal.c:1356: "!journal->j_checkpoint_transactions"
kernel: Kernel panic: Fatal exception
for a truly readonly underlying device, it's reasonable and necessary
to just skip orphan list processing.

When kernel is compiled with old version of autofs (CONFIG_AUTOFS_FS), and
new (observed at least with 5.x.x) automount deamon is started, kernel
correctly reports incompatible version of kernel and userland daemon, but
then screws things up instead of correct handling of the error:
autofs: kernel does not match daemon version

automount/4199 is trying to release lock (&type->s_umount_key) at:

=======================
and then deadlock comes.
The problem: autofs_fill_super() returns EINVAL to get_sb_nodev(), but
before that, it calls kill_anon_super() to destroy the superblock which
won't be needed. This is however way too soon to call kill_anon_super(),
because get_sb_nodev() has to perform its own cleanup of the superblock
first (deactivate_super(), etc.). The correct time to call
kill_anon_super() is in the autofs_kill_sb() callback, which is called by
deactivate_super() at proper time, when the superblock is ready to be
killed.
I can see the same faulty codepath also in autofs4. This patch solves
issues in both filesystems in a same way - it postpones the
kill_anon_super() until the proper time is signalized by deactivate_super()
calling the kill_sb() callback.

In the current jbd code, if a buffer on BJ_SyncData list is dirty and not
locked, the buffer is refiled to BJ_Locked list, submitted to the IO and
waited for IO completion.
But the fsstress test showed the case that when a buffer was already
submitted to the IO just before the buffer_dirty(bh) check, the buffer was
not waited for IO completion.
Following patch solves this problem. If it is assumed that a buffer is
submitted to the IO before the buffer_dirty(bh) check and still being
written to disk, this buffer is refiled to BJ_Locked list.

We add a save link for O_DIRECT writes to protect the i_size against the
crashes before we actually finish the I/O. If we hit an -ENOSPC in
aops->prepare_write(), we would do a truncate() to release the blocks which
might have got initialized. Now the truncate would add another save link
for the same inode causing a reiserfs panic for having multiple save links
for the same inode.

Some dentries don't need to be globally visible in dentry hashtable.
(pipes & sockets)
Such dentries dont need to wait for a RCU grace period at delete time.
Being able to free them permits a better CPU cache use (hot cache)
This patch combined with (dont insert pipe dentries into dentry_hashtable)
reduced time of { pipe(p); close(p[0]); close(p[1]);} on my UP machine (1.6
GHz Pentium-M) from 3.23 us to 2.86 us (But this patch does not depend on
other patches, only bench results)

We currently insert pipe dentries into the global dentry hashtable. This
is suboptimal because there is currently no way these entries can be used
for a lookup(). (/proc/xxx/fd/xxx uses a different mechanism). Inserting
them in dentry hashtable slows dcache lookups.
To let __dpath() still work correctly (ie not adding a " (deleted)") after
dentry name, we do :
- Right after d_alloc(), pretend they are hashed by clearing the
DCACHE_UNHASHED bit.
- Call d_instantiate() instead of d_add() : dentry is not inserted in
hash table.
__dpath() & friends work as intended during dentry lifetime.
- At dismantle time, once dput() must clear the dentry, setting again
DCACHE_UNHASHED bit inside the custom d_delete() function provided by
pipe code, so that dput() can just kill_it.
This patch, combined with (avoid RCU for never hashed dentries) reduced
time of { pipe(p); close(p[0]); close(p[1]);} on my UP machine (1.6GHz
Pentium-M) from 3.23 us to 2.86 us (But this patch does not depend on other
patches, only bench results)

There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,
prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus
generating compiler warnings of unused symbols, hence forcing people to add

the compiler can skip truly unused functions just fine:

Steve Grubb's fzfuzzer tool (http://people.redhat.com/sgrubb/files/
fsfuzzer-0.6.tar.gz) generates corrupt Cramfs filesystems which cause
Cramfs to kernel oops in cramfs_uncompress_block(). The cause of the oops
is an unchecked corrupted block length field read by cramfs_readpage().
This patch adds a sanity check to cramfs_readpage() which checks that the
block length field is sensible. The (PAGE_CACHE_SIZE << 1) size check is
intentional, even though the uncompressed data is not going to be larger
than PAGE_CACHE_SIZE, gzip sometimes generates compressed data larger than
the original source data. Mkcramfs checks that the compressed size is
always less than or equal to PAGE_CACHE_SIZE << 1. Of course Cramfs could
use the original uncompressed data in this case, but it doesn't.
