[GIT PULL] superblock scalability patches

[GIT PULL] superblock scalability patches

[Josef Bacik]

Hello,

Al would you please consider pulling from

git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-next.git 
superblock-scaling

I've rebased them onto Linus's master as of a few days ago and retested 
them to make sure they were still good to go.  They've all been through 
a lengthy review process and thoroughly tested.  The only change since 
the last time I posted the patch series is I've dropped the patch that 
created a new writeback list for sync to process because of the new 
writeback changes.  Porting that patch over is going to take some extra 
work and I don't want to hold up the rest of these patches any longer. 
Thanks,

Josef

Been testing this for a day now, it seems to be fine. The patch that
is missingis the really important scalability fix (i.e. the one that
avoids the entire inode cache walk to find dirty inodes), but I can
live with that being delayed to get all the prep merged sooner.

Thanks, Josef!
