2.6.32 will feature FUSE proto 7.13 which lets us tune the maximal number of

* fix in stripe readv, so that a read request which falls in
two (or more) subvolumes, depending on stripe-size works fine.

The problem: If some files on the first subvolume disappeared
without leaving a trace in the entry changelog (this can happen,
for example, when an fsck has deleted files or when a hard drive
is replaced), those files would never be self-healed even though
they would be present on the second subvolume. This is because
readdir is sent only to the first subvolume, and since the files
don't appear in the directory listing, no lookup would ever be
sent on them.
This patch fixes this problem by doing a readdir on all the subvolumes
during the first opendir on a directory inode. If a discrepancy in the
contents is detected, entry self-heal in a special "force merge" mode
is triggered on that directory.

If entry self-heal determines that a file/directory should
be deleted from a subvolume, move that entry to a directory
called "/.trash" on that subvolume. This is for two reasons:
1) It limits the damage that can be done by a "wrong" entry
self-heal.
2) It solves the problem of a to-be-deleted directory not
being empty.

- the earlier hash function does not distribute pages uniformly for offsets that
fit into 32 bits. The reason is that the hash function just xors the contents of
the key 4 bytes at a time with the current value of hash. Hence for keys that
fit into 32 bits, the hash will be the key itself. Since we are using the
rounded_offset (which is a multiple of 128KB) as the key, the key will
be exactly divisible by the number of buckets configured (4096) resolving all
the pages into the first bucket.
