This by itself doesn't fix the problem of too-fast timeout errors on soft mounts (e.g. returning EIO within <0.1s).
I am still seeing the fs get into a state where each time a large file is written, it reports EIO (but writes successfully anyway). And "ls -R" still shows EIO errors also.

I haven't tried this yet. It doesn't apply to 2.5.74 due to the calls to io_schedule().
