The comment is no longer true as (now that the BKL conversion is finished) a spinlock _is_ now used to protect file_lock_list, blocked_list and inode->i_flock. Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* 'for-2.6.38' of git://linux-nfs.org/~bfields/linux: (62 commits) nfsd4: fix callback restarting nfsd: break lease on unlink, link, and rename nfsd4: break lease on nfsd setattr nfsd: don't support msnfs export option nfsd4: initialize cb_per_client nfsd4: allow restarting callbacks nfsd4: simplify nfsd4_cb_prepare nfsd4: give out delegations more quickly in 4.1 case nfsd4: add helper function to run callbacks nfsd4: make sure sequence flags are set after destroy_session nfsd4: re-probe callback on connection loss nfsd4: set sequence flag when backchannel is down nfsd4: keep finer-grained callback status rpc: allow xprt_class->setup to return a preexisting xprt rpc: keep backchannel xprt as long as server connection rpc: move sk_bc_xprt to svc_xprt nfsd4: allow backchannel recovery nfsd4: support BIND_CONN_TO_SESSION nfsd4: modify session list under cl_lock Documentation: fl_mylease no longer exists ... Fix up conflicts in fs/nfsd/vfs.c with the vfs-scale work. The vfs-scale work touched some msnfs cases, and this merge removes support for that entirely, so the conflict was trivial to resolve.
Make d_count non-atomic and protect it with d_lock. This allows us to ensure a 0 refcount dentry remains 0 without dcache_lock. It is also fairly natural when we start protecting many other dentry members with d_lock. Signed-off-by: Nick Piggin <npiggin@kernel.dk>

The nfs server only supports read delegations for now, so we don't care how conflicts are determined. All we care is that unlocks are recognized as matching the leases they are meant to remove. After the last patch, a comparison of struct files will work for that purpose. So we no longer need this callback. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
A minor oversight from f7347ce4ee7c65415f84be915c018473e7076f31, "fasync: re-organize fasync entry insertion to allow it under a spinlock": this cleanup-on-error was only needed to handle -ENOMEM. Now that we're preallocating it's unneeded. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
We must also free the passed-in lease in the case it wasn't used because an existing lease was upgrade/downgraded or already existed. Note the nfsd caller doesn't care because it's fl_change callback returns an error in those cases. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
