[GIT PULL v3] Btrfs: improve write ahead log with sub transaction
I''ve been working to try to improve the write-ahead log''s performance,
and I found that the bottleneck addresses in the checksum items,
especially when we want to make a random write on a large file, e.g a 4G file.
Then a idea for this suggested by Chris is to use sub transaction ids and just
to log the part of inode that had changed since either the last log commit or
the last

[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
