A problem with tree mounts expiring from under a process has uncovered a
couple of problems with the autofs4 module. These patches are a result of the investigation.
1) autofs4-2.6.12-rc1-mm4-wait-order.patch
It's possible for an event wait request to arive before the event requestor. If this happens the daemon never gets notified and autofs hangs.
2) autofs4-2.6.12-rc1-mm4-tree-race.patch
For tree mount maps, a call to chdir or chroot, to a directory above the
moint point directories at a certain time during the expire results in the expire incorrectly thinking the tree is not busy. This patch adds a check to see if the filesystem above the tree mount points is busy and also locks the filesystem during the tree mount expire to prevent the race.
3) autofs4-2.6.12-rc1-mm4-version.patch
Bump autofs4 version so we know what's going on.
