[PATCH] knfsd: stop NFSD writes from being broken into lots of little writes to filesystem
When NFSD receives a write request, the data is typically in a number of
1448 byte segments and writev is used to collect them together.
Unfortunately, generic_file_buffered_write passes these to the filesystem
one at a time, so an e.g. 32K over-write becomes a series of partial-page
writes to each page, causing the filesystem to have to pre-read those pages
- wasted effort.
generic_file_buffered_write handles one segment of the vector at a time as
it has to pre-fault in each segment to avoid deadlocks. When writing from
kernel-space (and nfsd does) this is not an issue, so
generic_file_buffered_write does not need to break and iovec from nfsd into
little pieces.
This patch avoids the splitting when get_fs is KERNEL_DS as it is
from NFSd.

That's fine, but we're doing that by inserting a deny after *every* allow,

make no difference.

The rfc allows us to be more permissive about the ACL inheritance bits we
accept:
"If the server supports a single "inherit ACE" flag that applies to
both files and directories, the server may reject the request
(i.e., requiring the client to set both the file and directory
inheritance flags). The server may also accept the request and
silently turn on the ACE4_DIRECTORY_INHERIT_ACE flag."
Let's take the latter option--the ACL is a complex attribute that could be
rejected for a wide variety of reasons, and the protocol gives us little
ability to explain the reason for the rejection, so erroring out is a
user-unfriendly last resort.

[PATCH] Add debugging feature /proc/timer_stat
Add /proc/timer_stats support: debugging feature to profile timer expiration.
Both the starting site, process/PID and the expiration function is captured.
This allows the quick identification of timer event sources in a system.
Sample output:
# echo 1 > /proc/timer_stats
# cat /proc/timer_stats
Timer Stats Version: v0.1
Sample period: 4.010 s
