the pagebuf had been unlocked if the buffer was delwri. At high load, this
could result in a race when the superblock was being synced that would
result the flags being incorrect and the iodone functions being executed
incorrectly. This then leads to iclog callback failures or AIL list
corruptions resulting in filesystem shutdowns.

which can cause an extent hole to be filled and a free extent to be
processed. In this case, we make a few mistakes: forget to pass back the
transaction, forget to put a hold on the buffer and forget to add the buf
to the new transaction.

because aio+dio completions may happen from irq context but we need
process context for converting unwritten extents. We also queue regular
direct I/O completions to workqueue for regularity, there's only one
queue_work call per syscall.

Use MAP_PRIVATE when calling mmap to get memory for the code region.
The flat loader was using MAP_SHARED, but underlying changes to the
MMUless mmap means this is now wrong.

log changes went in. The symptom was the msg of "xfs_log_write:
reservation ran out. Need to up reservation" and was seen on synchronous
writes on files with lots of holes (and therefore lots of extents).

Since the patch to add a NULL short-circuit to crypto_free_tfm() went in,
there's no longer any need for callers of that function to check for NULL.
This patch removes the redundant NULL checks and also a few similar checks
for NULL before calls to kfree() that I ran into while doing the
crypto_free_tfm bits.
I've succesfuly compile tested this patch, and a kernel with the patch
applied boots and runs just fine.
When I posted the patch to LKML (and other lists/people on Cc) it drew the
following comments :
J. Bruce Fields commented
"I've no problem with the auth_gss or nfsv4 bits.--b."
Sridhar Samudrala said
"sctp change looks fine."
Herbert Xu signed off on the patch.
So, I guess this is ready to be dropped into -mm and eventually mainline.
