[PATCH] fs: push file_update_time into ->page_mkwrite
The fault code has been calling file_update_time after ->page_mkwrite after it
drops the page lock, but this is annoying because this calls mark_inode_dirty
which can fail in Btrfs, so we want to be able to do these updates in
->page_mkwrite so we can get an error back to the user. So get rid of the
file_update_time calls in the fault code...

[Patch] btrfs: use file_remove_suid() after i_mutex is held
file_remove_suid() should be called with i_mutex held,
file_update_time() too. So move them after mutex_lock().
Plus, check the return value of kmalloc().

btrfs hang in flush-btrfs-5
Hi - I''m trying btrfs with kernel 2.6.38.8-32.fc15.x86_64 (a Fedora kernel).
I''m just doing a tar-to-tar copy onto the file system with compress-
force=zlib. Here are some traces of the stuck processes.

[PATCH 1/5] 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
