[PATCH] fuse: fix Oops in lookup
Fix bug in certain error paths of lookup routines. The request object was
reused for sending FORGET, which is illegal. This bug could cause an Oops
in 2.6.18. In earlier versions it might silently corrupt memory, but this
is very unlikely.
These error paths are never triggered by libfuse, so this wasn't noticed
even with the 2.6.18 kernel, only with a filesystem using the raw kernel
interface.
Thanks to Russ Cox for the bug report and test filesystem.
