08fa159003 [ARM] sa1111: avoid using hardcoded IRQ numbers for PCMCIA driver
The IRQs for card detect and status change are currently hardcoded in
SA1111 PCMCIA driver, which can be actually obtained from the .irq[]
from 'struct sa1111_dev' to keep it generic.

00dd8027b9 [ARM] locomo: remove unused IRQs and avoid unnecessary cascade
IRQ_LOCOMO_* are never used elsewhere, remove these definitions. As well
as the cascade of these IRQs. IRQ_LOCOMO_*_BASE changed to IRQ_LOCOMO_*.

IRQ_LOCOMO_LT and IRQ_LOCOMO_SPI are likely to be used in a same way as
IRQ_LOCOMO_KEY.

IRQ_LOCOMO_GPIO and the demultiplex handler should really be living
somewhere else.

e9964c1023 ceph: fix flush_dirty_caps race with caps migration
The flush_dirty_caps() used to loop over the first entry of the cap_dirty
dirty list on the assumption that after calling ceph_check_caps() it would
be removed from the list.  This isn't true for caps that are being
migrated between MDSs, where we've received the EXPORT but not the IMPORT.

Instead, do a safe list iteration, and pin the next inode on the list via
the CEPH_I_NOFLUSH flag.

77d7a0c2ee xfs: Non-blocking inode locking in IO completion
The introduction of barriers to loop devices has created a new IO
order completion dependency that XFS does not handle. The loop
device implements barriers using fsync and so turns a log IO in the
XFS filesystem on the loop device into a data IO in the backing
filesystem. That is, the completion of log IOs in the loop
filesystem are now dependent on completion of data IO in the backing
filesystem.

This can cause deadlocks when a flush daemon issues a log force with
an inode locked because the IO completion of IO on the inode is
blocked by the inode lock. This in turn prevents further data IO
completion from occuring on all XFS filesystems on that CPU (due to
the shared nature of the completion queues). This then prevents the
log IO from completing because the log is waiting for data IO
completion as well.

The fix for this new completion order dependency issue is to make
the IO completion inode locking non-blocking. If the inode lock
can't be grabbed, simply requeue the IO completion back to the work
queue so that it can be processed later. This prevents the
completion queue from being blocked and allows data IO completion on
other inodes to proceed, hence avoiding completion order dependent
deadlocks.

a9cc799eca xfs: increase readdir buffer size
While doing some testing of readdir perf a while back,
I noticed that the buffer size we're using internally is
smaller than what glibc gives us by default.  Upping this
size helped a bit, and seems safe.

glibc's __alloc_dir() does:

  const size_t default_allocation = (4 * BUFSIZ < sizeof (struct dirent64)
                                     ? sizeof (struct dirent64) : 4 * BUFSIZ);
  const size_t small_allocation = (BUFSIZ < sizeof (struct dirent64)
                                   ? sizeof (struct dirent64) : BUFSIZ);
  size_t allocation = default_allocation;
#ifdef _STATBUF_ST_BLKSIZE
  if (statp != NULL && default_allocation < statp->st_blksize)
    allocation = statp->st_blksize;
#endif

and

#define _G_BUFSIZ 8192
#define _IO_BUFSIZ _G_BUFSIZ
# define BUFSIZ _IO_BUFSIZ

so the default buffer is 4 * 8192 = 32768
(except in the unlikely case of blocks > 32k....)

When writing a disc on certain lite-on dvd-writers (also rebadged

Delaying between sending the CDB and starting DMA seems to

4b7d1c0509 ata: Detect Delkin Devices compact flash
I have a Delkin Devices compact flash card that isn't being recognized using the
SATA/PATA drivers.
The card is recognized and works with the deprecated ATA drivers.

The error I am seeing is:
ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0)

I tracked it down to ata_id_is_cfa() in include/linux/ata.h.
The Delkin card has id[0] set to 0x844a and id[83] set to 0.
This isn't what the kernel expects and is probably incorrect.

The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().

7e044a12c7 pata_efar: Enable parallel scanning
Again originally proposed by Bartlomiej but this does it by using the
generic helper logic instead.

1d3a8118b0 pata_atiixp: enable parallel scan
This was originally proposed by Bartlomiej but as a device specific
expansion of the init_one function rather than making the helper more
generic.

Enable the parallel scan via the generic flags.

e99846f18f [libata] pata_atiixp: add locking for parallel scanning
This is similar change as commit 60c3be3 for ata_piix host driver
and while pata_atiixp doesn't enable parallel scan yet the race
could probably also be triggered by requesting re-scanning of both
ports at the same time using SCSI sysfs interface.
