Revision 255129d1e9ca0ed3d69d5517fae3e03d7ab4b806 authored by Trond Myklebust on 25 September 2007, 19:55:03 UTC, committed by Linus Torvalds on 26 September 2007, 16:22:04 UTC
The problem is that the garbage collector for the 'host' structures
nlm_gc_hosts(), holds nlm_host_mutex while calling down to
nlmsvc_mark_resources, which, eventually takes the file->f_mutex.

We cannot therefore call nlmsvc_lookup_host() from within
nlmsvc_create_block, since the caller will already hold file->f_mutex, so
the attempt to grab nlm_host_mutex may deadlock.

Fix the problem by calling nlmsvc_lookup_host() outside the file->f_mutex.
