2.6.18-stable review patch. If anyone has any objections, please let us know.
------------------
From: Milan Broz <[email protected]>
Fix oops when removing full snapshot
kernel bugzilla bug 7040
If a snapshot became invalid (full) while there is outstanding
pending_exception, pending_complete() forgets to remove
the corresponding exception from its exception table before freeing it.
Already fixed in 2.6.19.
