Since CONFIG_RAMFS is currently hard-selected to "y", and since
Documentation/filesystems/ramfs-rootfs-initramfs.txt reads as follows:

"The amount of code required to implement ramfs is tiny, because all the
work is done by the existing Linux caching infrastructure.  Basically,
you're mounting the disk cache as a filesystem.  Because of this, ramfs is
not an optional component removable via menuconfig, since there would be
negligible space savings."

It seems pointless to leave this as a Kconfig entry.

This fixes a problem with the way cciss was filling out the "errors" field
of the request structure upon completion of requests.  Previously, it just
put a 1 or a 0 in there and used the negation of this as the uptodate
parameter to one of the functions in the block layer, being a block device.
 For the SG_IO ioctl, this was not sufficient, and we noticed that, for
example, sg_turs from sg3_utils did not correctly detect problems due to
cciss having set rq->errors incorrectly.

Allow NBD I/O to be cancelled when a network outage occurs.  Previously, I/O
would just hang, and if enough I/O was hung in nbd, the system (at least
user-level) would completely hang until a TCP timeout (default, 15 minutes)
occurred.

The patch introduces a new ioctl NBD_SET_TIMEOUT that allows a transmit
timeout value (in seconds) to be specified.  Any network send that exceeds the
timeout will be cancelled and the nbd connection will be shut down.  I've
tested with various timeout values and 6 seconds seems to be a good choice for
the timeout.  If the NBD_SET_TIMEOUT ioctl is not called, you get the old (I/O
hang) behavior.

This patch set frees the restriction that makedumpfile users should install a
vmlinux file (including the debugging information) into each system.

makedumpfile command is the dump filtering feature for kdump.  It creates a
small dumpfile by filtering unnecessary pages for the analysis.  To
distinguish unnecessary pages, it needs a vmlinux file including the debugging
information.  These days, the debugging package becomes a huge file, and it is
hard to install it into each system.

To solve the problem, kdump developers discussed it at lkml and kexec-ml.  As
the result, we reached the conclusion that necessary information for dump
filtering (called "vmcoreinfo") should be embedded into the first kernel file
and it should be accessed through /proc/vmcore during the second kernel.

There is no any reason to do recalc_sigpending() after changing ->sighand.
To begin with, recalc_sigpending() does not take ->sighand into account.

This means we don't need to take newsighand->siglock while changing sighands.
rcu_assign_pointer() provides a necessary barrier, and if another process
reads the new ->sighand it should either take tasklist_lock or it should use
lock_task_sighand() which has a corresponding smp_read_barrier_depends().

Fix f_version type: should be u64 instead of long

There is a type inconsistency between struct inode i_version and struct file
f_version.

fs.h:

struct inode
  u64                     i_version;

and

struct file
  unsigned long           f_version;

Users do:

fs/ext3/dir.c:

if (filp->f_version != inode->i_version) {

So why isn't f_version a u64 ? It becomes a problem if versions gets
higher than 2^32 and we are on an architecture where longs are 32 bits.

This patch changes the f_version type to u64, and updates the users accordingly.

It applies to 2.6.23-rc2-mm2.

Lomesh reported poll returning EINTR during suspend/resume cycle.  This is
caused by the STOP/CONT cycle that the freezer uses, generating a pending
signal for what in effect is an ignored signal.  In general poll is a
little eager in returning EINTR, when it could try not bother userspace and
simply restart the syscall.  Both select and ppoll do use ERESTARTNOHAND to
restart the syscall.  Oleg points out that simply using ERESTARTNOHAND will
cause poll to restart with original timeout value.  which could ultimately
lead to process never returning to userspace.  Instead use
ERESTART_RESTARTBLOCK, and restart poll with updated timeout value.
Inspired by Manfred's use ERESTARTNOHAND in poll patch.
