ext4: allow specifying external journal by pathname mount option (2013-08-28 19:05:07 -0400)
----------------------------------------------------------------
New features for 3.12:
* Added aggressive extent caching using the extent status tree. This
can actually decrease memory usage in read-mostly workloads since
the information is much more compactly stored in the extent status
tree than if we had to keep the extent tree metadata blocks in the
buffer cache. This also improves Asynchronous I/O since it is it
makes much less likely that we need to do metadata I/O to lookup the
extent tree information.
* Improve the recovery after corrupted allocation bitmaps are found
when running in errors=ignore mode.
Also fixed some writeback vs. truncate races when using a blocksize
less than the page size.
