Fat is commonly used on removable media. Mounting with -o flush tells the
FS to write things to disk as quickly as possible. It is like -o sync, but
much faster (and not as safe).

Need to enable/disable all the counters instead of just counter 0.
This affects all cpus with family=6, including i386/core. Usual symptom:
only counter 0 provides samples. Other counters don't produce samples.

[assuming BSD security levels are deleted]
The only user of i_security, f_security, s_security fields is SELinux,
however, quite a few security modules are trying to get into kernel.
So, wrap them under CONFIG_SECURITY. Adding config option for each
security field is likely an overkill.
Following Stephen Smalley's suggestion, i_security initialization is
moved to security_inode_alloc() to not clutter core code with ifdefs
and make alloc_inode() codepath tiny little bit smaller and faster.
The user of (highly greppable) struct fown_struct::security field is
still to be found. I've checked every "fown_struct" and every "f_owner"
occurence. Additionally it's removal doesn't break i386 allmodconfig
build.
struct inode, struct file, struct super_block, struct fown_struct
become smaller.
P.S. Combined with two reiserfs inode shrinking patches sent to
linux-fsdevel, I can finally suck 12 reiserfs inodes into one page.

ReiserFS does periodic cleanup of old transactions in order to limit the
length of time a journal replay may take after a crash. Sometimes, writing
metadata from an old (already committed) transaction may require committing
a newer transaction, which also requires writing all data=ordered buffers.
This can cause very long stalls on journal_begin.
This patch makes sure new transactions will not need to be committed before
trying a periodic reclaim of an old transaction. It is low risk because if
a bad decision is made, it just means a slightly longer journal replay
after a crash.

Fix utf-8 mode so alternate charset modes always work according to control
sequences interpreted in do_con_trol function preserving backward US-ASCII
and VT100 semigraphics compatibility.
Malformed utf-8 sequences are represented as sequences of replacement
glyphs,original codes or '?' as a last resort.
unicode-xterm, gnome-terminal, kconsole and other terminal emulators in
utf-8 mode respect acsc, enacs, rmacs sequences. Also I found that some
important system programs (from Debian distro) uses acsc in utf-8 mode -
dselect, aptitude, w3m for example.

In cases where we detect a single bit has been flipped, we spew the usual
slab corruption message, which users instantly think is a kernel bug. In a
lot of cases, single bit errors are down to bad memory, or other hardware
failure.
This patch adds an extra line to the slab debug messages in those cases, in
the hope that users will try memtest before they report a bug.
000: 6b 6b 6b 6b 6a 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b

Oleg brought up some interesting points about grabbing the pi_lock for some
protections. In this discussion, I realized that there are some places
that the pi_lock is being grabbed when it really wasn't necessary. Also
this patch does a little bit of clean up.
This patch basically does three things:
1) renames the "boost" variable to "chain_walk". Since it is used in
the debugging case when it isn't going to be boosted. It better
describes what the test is going to do if it succeeds.
2) moves get_task_struct to just before the unlocking of the wait_lock.
This removes duplicate code, and makes it a little easier to read. The
owner wont go away while either the pi_lock or the wait_lock are held.
3) removes the pi_locking and owner blocked checking completely from the
debugging case. This is because the grabbing the lock and doing the
check, then releasing the lock is just so full of races. It's just as
good to go ahead and call the pi_chain_walk function, since after
releasing the lock the owner can then block anyway, and we would have
missed that. For the debug case, we really do want to do the chain walk
to test for deadlocks anyway.

Previously, since determination whether there was an Intel random number
generator was based on a single bit, on systems with a matching bridge
device but without a firmware hub, there was a 50% chance that the code
would incorrectly decide that the system had an RNG. This patch adds
detection of the firmware hub to better qualify the existence of an RNG.
There is one issue with the patch: I was unable to determine the LPC
equivalent for the PCI bridge 8086:2430 (since the old code didn't care
about which of the many devices provided by the ICH/ESB it was chose to use
the PCI bridge device, but the FWH settings live in the LPC device, so the
device list needed to be changed).

There's a bug where a UDF_PART_FLAG_READ_ONLY udf partition gets mounted
read-write, then subsequent problems happen; files seem to be able to be
removed, but file creation results in EIO or worse, oops.
EIO is coming from udf_new_block(), which returns EIO if the right flags
aren't set; only UDF_PART_FLAG_READ_ONLY is set in this case. We probably
s hould not have gotten this far...
Attached patch seems to fix it - and includes a printk to alert the user
that their "rw" mount request has been converted to "ro."

The on-disk data structures from AIX are not known, also the filesystem
layout is not known. There is a msdos partition signature at the end of
the first block, and the kernel recognizes 3 small (and overlapping)
partitions. But they are not usable. Maybe the firmware uses it to find
the bootloader for AIX, but AIX boots also if the first block is cleared.
This is the content of the partition table:
# dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) | xxd
0000000: 0000 0000 0000 0000 0000 0000 0000 0000 ................
0000010: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8...
0000020: 00ff ffff 41ff ffff 0211 0000 1900 0000 ....A...........
0000030: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8...
Handle the whole disk as empty disk.
This fixes also YaST which compares the output from parted (and formerly
fdisk) with /proc/partitions. fdisk recognizes the AIX label since a long
time, SuSE has a patch for parted to handle the disk label as unknown.
dmesg will look like this:

This teaches dmi_decode() how to decode and save OEM Strings (type 11) DMI
information, which is currently discarded silently. Existing code using
DMI is not affected. Follows the "System Management BIOS (SMBIOS)
Specification" (http://www.dmtf.org/standards/smbios), and also the
userspace dmidecode.c code.
OEM Strings are the only safe way to identify some hardware, e.g., the
ThinkPad embedded controller used by the soon-to-be-submitted tp_smapi
driver. This will also let us eliminate the long whitelist in the mainline
hdaps driver (in a future patch).

can be the case for a network filesystem exported by an unprivileged server

Initialize module_subsys earlier (or at least earlier than devices) since
it could be used very early in the boot process if kmod loads a module
before the device initcalls. Otherwise, kmod will crash in
kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not
initialized yet.
I only noticed this problem because occasionally, kmod loads the modules
for my SCSI and Ethernet adapters very early, during the boot process
itself. I don't quite understand why it loads them sometimes and doesn't
load them other times. Or who is telling kmod to do so. Can someone

Only compile with -O1 if the (very old) compiler is broken. We use
reiserfs alot since SLES9 on ppc64, and it was never seen with gcc33.
Assume the broken gcc is gcc-3.4 or older.

In spinlock_debug.c, the spinloops call __delay() on every iteration.
Because that is an external function, (jiffies_per_loop * HZ), the loop's
iteration limit, gets recomputed every time. Caching it explicitly
prevents that.
