Hi,
This all looks good to me, so now we just need lots of testing. Are you
still seeing good speed ups vs the current code?

This is my latest version of this patchset based on inputs from Andreas
and Steve.
We readahead the journal sequentially in large chunks using bios. Pagecache
pages for the journal inode's mapping are used for the I/O.
There's also some cleanup of the bio functions with this patchset.
xfstests ran to completion with this.
Abhi Das (4):
gfs2: add more timing info to journal recovery process
gfs2: changes to gfs2_log_XXX_bio
gfs2: add a helper function to get_log_header that can be used
elsewhere
gfs2: read journal in large chunks to locate the head
