2006-10-04[PATCH] Convert lockd to use the newer mutex instead of the older semaphoreNeil Brown
Both the (recently introduces) nsm_sema and the older f_sema are converted over. Cc: Olaf Kirch <okir@suse.de> Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-10-04[PATCH] knfsd: simplify nlmsvc_invalidate_allNeilBrown
As a result of previous patches, the loop in nlmsvc_invalidate_all just sets h_expires for all client/hosts to 0 (though does it in a very complicated way). This was possibly meant to trigger early garbage collection but half the time '0' is in the future and so it infact delays garbage collection. Pre-aging the 'hosts' is not really needed at this point anyway so we throw out the loop and nlm_find_client which is no longer needed.

2006-10-04[PATCH] knfsd: lockd: make nlm_traverse_* more flexibleOlaf Kirch
This patch makes nlm_traverse{locks,blocks,shares} and friends use a function pointer rather than a "action" enum. This function pointer is given two nlm_hosts (one given by the caller, the other taken from the lock/block/share currently visited), and is free to do with them as it wants. If it returns a non-zero value, the lockd/block/share is released.

2006-10-04[PATCH] knfsd: change nlm_file to use a hlistOlaf Kirch
This changes struct nlm_file and the nlm_files hash table to use a hlist instead of the home-grown lists. This allows us to remove f_hash which was only used to find the right hash chain to delete an entry from. It also increases the size of the nlm_files hash table from 32 to 128.

2006-08-24LOCKD: Fix a deadlock in nlm_traverse_files()Trond Myklebust
nlm_traverse_files() is not allowed to hold the nlm_file_mutex while calling nlm_inspect file, since it may end up calling nlm_release_file() when releaseing the blocks. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> (cherry picked from e558d3cde986e04f68afe8c790ad68ef4b94587a commit)

2006-03-20lockd: Remove FL_LOCKD flagJ. Bruce Fields
Currently lockd identifies its own locks using the FL_LOCKD flag. This doesn't scale well to multiple lock managers--if we did this in nfsv4 too, for example, we'd be left with only one free flag bit. Instead, we just check whether the file manager ops (fl_lmops) set on this lock are our own. The only use for this is in nlm_traverse_locks, which uses it to find locks that need cleaning up when freeing a host or a file. In the long run it might be nice to do reference counting instead of traversing all the locks like this.... Signed-off-by: J.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
