You'd have to drop the next two ext4 -stable patches to get a buildable kernel if you drop this one. The last of those ext4 patches is the one which fixes the deadlock from kernel bugzilla #12579.

I'll nominate Ted's "ext4: Use our own write_cache_pages()" patch for ..27-stable when it hits mainline. If it is included in -stable, then those last two ext4 patches can be re-applied. > Personally, I doubt many people care about ext4 on the .27 kernel > release... In any case, 2.6.27 is a good kernel, and ext4 is a good FS, IMO.
