[PATCH] elevator=as back-compatibility
As of 2.6.15 you need to use "anticipatory" instead of "as". Fix that up
so that `elevator=as' still works.

[PATCH] fuse: fix bitfield race
Fix race in setting bitfields of fuse_conn. Spotted by Andrew Morton.
The two fields ->connected and ->mounted were always changed with the
fuse_lock held. But other bitfields in the same structure were changed
without the lock. In theory this could lead to losing the assignment of
even the ones under lock. The chosen solution is to change these two
fields to be a full unsigned type. The other bitfields aren't "important"
enough to warrant the extra complexity of full locking or changing them to
bitops.
For all bitfields document why they are safe wrt. concurrent
assignments.
Also make the initialization of the 'num_waiting' atomic counter explicit.

[PATCH] fuse: add connection aborting
Add ability to abort a filesystem connection.
With the introduction of asynchronous reads, the ability to interrupt any
request is not enough to dissolve deadlocks, since now waiting for the request
completion (page unlocked) is independent of the actual request, so in a
deadlock all threads will be uninterruptible.
The solution is to make it possible to abort all requests, even those
currently undergoing I/O to/from userspace. The natural interface for this is
'mount -f mountpoint', but that only works as long as the filesystem is
attached. So also add an 'abort' attribute to the sysfs view of the
connection.
