[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
compressed or

[patch 00/65] Error handling patchset v3
Hi all -
Here''s my current error handling patchset, against 3.1-rc8. Almost all of
this patchset is preparing for actual error handling. Before we start in
on that work, I''m trying to reduce the surface we need to worry about. It
turns out that there is a ton of code that returns an error code but never
actually reports an error.
The patchset has grown to 65 patches. 46 of them
