If CONFIG_DEBUG_FS=y debugfs functions will never return an

Update the code to reflect this. We gain an extra dentry pointer

The patch series to re-factor PCI's 'latency timer' setup (re:
http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to
remove the ARM specific definition of 'pcibios_max_latency' once such
had been moved into the pci core resulting in ARM related compile
errors -
drivers/built-in.o:(.data+0x230): multiple definition of
`pcibios_max_latency'
arch/arm/common/built-in.o:(.data+0x40c): first defined here
make[1]: *** [vmlinux.o] Error 1
In the series, patch 2/16 (commit 168c8619fd) converted the ARM
specific version of 'pcibios_set_master()' to a non-inlined version.
This was done in preperation for hosting it up into PCI's core, which
was done in patch 10/16 (commit 96c5590058) of the series (and
where the removal of ARM's 'pcibios_max_latency' was overlooked).

When the MCLK is used to drive the Audio Clock Regeneration packets,

the TMDS clock directly by leaving ACR_CTRL[2] set to 0.
The MLCK clock divisor, mclk_mode, is configured only if MLCK
is used. Such configuration is no longer related to the CTS mode
as in some silicon revisions CTS SW-mode is used along with the MCLK.

Processes hang forever on a sync-mounted ext2 file system that
is mounted with the ext4 module (default in Fedora 16).
I can reproduce this reliably by mounting an ext2 partition with
"-o sync" and opening a new file an that partition with vim. vim
will hang in "D" state forever. The same happens on ext4 without
a journal.
I am attaching a small patch here that solves this issue for me.
In the sync mounted case without a journal,
ext4_handle_dirty_metadata() may call sync_dirty_buffer(), which
can't be called with buffer lock held.
Also move mb_cache_entry_release inside lock to avoid race

When resizing file system in the way that the new size of the file
system is still in the same group (no new groups are added), then we can
hit a BUG_ON in ext4_alloc_group_tables()
BUG_ON(flex_gd->count == 0 || group_data == NULL);
because flex_gd->count is zero. The reason is the missing check for such
case, so the code always extend the last group fully and then attempt to
add more groups, but at that time n_blocks_count is actually smaller
than o_blocks_count.
It can be easily reproduced like this:
mkfs.ext4 -b 4096 /dev/sda 30M
mount /dev/sda /mnt/test
resize2fs /dev/sda 50M
Fix this by checking whether the resize happens within the singe group
and only add that many blocks into the last group to satisfy user
request. Then o_blocks_count == n_blocks_count and the resize will exit
successfully without and attempt to add more groups into the fs.
Also fix mixing together block number and blocks count which might be
confusing and can easily lead to off-by-one errors (but it is actually
not the case here since the two occurrence of this mix-up will cancel
each other).

If __print_flags() is used after another __print_*() function, the
temp seq_file buffer will not be empty on entry, and the delimiter will
be printed even though there's just one field. We get something like:
|S
instead of just:
S
This is because the length of the temp seq buffer is used to determine
if the delimiter is printed or not. But this algorithm fails when
the seq buffer is not empty on entry, and the delimiter will be printed
because it thinks that a previous field was already printed.

Linus noticed that the cmp used to check if the code segment is
__KERNEL_CS or not did not specify a size. Perhaps it does not matter
as H. Peter Anvin noted that user space can not set the bottom two
bits of the %cs register. But it's best not to let the assembly choose
and change things between different versions of gas, but instead just
pick the size.
Four bytes are used to compare the saved code segment against
__KERNEL_CS. Perhaps this might mess up Xen, but we can fix that when
the time comes.
Also I noticed that there was another non-specified cmp that checks
the special stack variable if it is 1 or 0. This too probably doesn't
matter what cmp is used, but this patch uses cmpl just to make it non
ambiguous.

The patch integrates FW 7.2.16 HSI and implements driver
part of GRO flow.
FW 7.2.16 adds the ability to aggregate packets for GRO
(and not just LRO) and also fixes some bugs.
1. Added new aggregation mode: GRO. In this mode packets are aggregated
such that the original packets can be reconstructed by the OS.
2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32.
3. Adding the FCoE statistics structures to the BNX2X HSI.
4. Wrong configuration of TX HW input buffer size may cause theoretical
performance effect. Performed configuration fix.
5. FCOE - Arrival of packets beyond task IO size can lead to crash.
Fix firmware data-in flow.
6. iSCSI - In rare cases of on-chip termination the graceful termination
timer hangs, and the termination doesn't complete. Firmware fix to MSL
timer tolerance.
7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles
open at the initiator side. Firmware implementation corrected to drop
FIN received out-of-order or with isles still open.
8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes
from the beginning of iSCSI PDU. Firmware implementation corrected
to support arbitrary aligned retransmissions.
9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic
might lead to crash. Firmware fix to relevant flow.

The following comment in ext4_end_io_dio caught my attention:
/* XXX: probably should move into the real I/O completion handler */
inode_dio_done(inode);
The truncate code takes i_mutex, then calls inode_dio_wait. Because the
ext4 code path above will end up dropping the mutex before it is
reacquired by the worker thread that does the extent conversion, it
seems to me that the truncate can happen out of order. Jan Kara
mentioned that this might result in error messages in the system logs,
but that should be the extent of the "damage."
The fix is pretty straight-forward: don't call inode_dio_done until the
extent conversion is complete.
