[PATCH] Change the check for PageReadahead into an else-if
From: Raghavendra D Prabhu <rprabhu@wnohang.net>
From 51daa88ebd8e0d437289f589af29d4b39379ea76, page_sync_readahead coalesces
async readahead into its readahead window, so another checking for that again is
not required.

[PATCH 1/4] fs: allow short direct-io reads to be completed via buffered IO V2
V1->V2: Check to see if our current ppos is >= i_size after a short DIO read,
just in case it was actually a short read and we need to just return.
This is similar to what already happens in the write case. If we have a short
read while doing O_DIRECT, instead of just returning, fallthrough and try to
read the rest via buffered IO. BTRFS needs this because if we encounter a

[PATCH] BUG on error handlings in Ext3 under I/O failure condition
Hello.
I found bugs on error handlings in the functions arround the ext3 file
system, which cause inadequate completions of synchronous write I/O operations
when disk I/O failures occur. Both 2.4 and 2.6 have this problem.
I carried out following experiment:
1. Mount a ext3 file system on a SCSI disk with ordered mode.
2. Open a file on the file system with O_SYNC|O_RDWR|O_TRUNC|O_CREAT

After way to many months here is the fifth version of the guest page
hinting patches. Compared to version four a few improvements have been
added:
- Avoid page_host_discards() calls outside of page-states.h
- The discard list is now implemented via the page_free_discarded
hook and architecture specific code.
- PG_state_change page flag has been replaced with architecture

[andrea@suse.de: Re: VFS bug in 2.4.10+ which applies ulimits to block devices]
I had sent email to Andrea asking him if his blkdev-in-pagecache might
cause the recent reports about ulimits being applied to block devices.
This is his response which he asked me to forward to ext3-users since he
can't post being a non-subscriber
BTW, Redhat should whitelist various kernel hackers email address on
their mailserver so that they can post freely to various lists
