I'm not even sure cl_xprt can change here, but we're getting "suspicious RCU usage" warnings, and other rpc_peeraddr2str callers are taking the rcu lock. Signed-off-by: -

'status' has been overwritten to 0 after nfsd4_ssc_setup_dul(), this cause 0 will be return in vfs_kern_mount() error case. Fix to return nfserr_nodev in this error. Fixes: f4e44b39 ("NFSD: delay unmount source's export after inter-server copy completed.") Reported-by:

Fix by initializing pointer nfsd4_ssc_umount_item with NULL instead of 0. Replace return value of nfsd4_ssc_setup_dul with __be32 instead of int. Reported-by:

This was causing a "sleeping function called from invalid context" warning. I don't think we need the set_and_test_bit() here; clients move from unconfirmed to confirmed only once, under the client_lock. The (conf == unconf) is a way to check whether we're in that confirming case, hopefully that's not too obscure. Fixes: 472d155a "nfsd: report client confirmation status in "info" file" Signed-off-by:

Currently the source's export is mounted and unmounted on every inter-server copy operation. This patch is an enhancement to delay the unmount of the source export for a certain period of time to eliminate the mount and unmount overhead on subsequent copy operations. After a copy operation completes, a work entry is added to the delayed unmount list with an expiration time. This list is serviced by the laundromat thread to unmount the export of the expired entries. Each time the export is being used again, its expiration time is extended and the entry is re-inserted to the tail of the list. The unmount task and the mount operation of the copy request are synced to make sure the export is not unmounted while it's being used. Signed-off-by:

Currently, the server does all copies as NFS_UNSTABLE. For synchronous copies linux client will append a COMMIT to the COPY compound but for async copies it does not (because COMMIT needs to be done after all bytes are copied and not as a reply to the COPY operation). However, in order to save the client doing a COMMIT as a separate rpc, the server can reply back with NFS_FILE_SYNC copy. This patch proposed to add vfs_fsync() call at the end of the async copy.

Truncation of an unlinked inode may take a long time for I/O waiting, and it doesn't have to prevent access to the directory. Thus, let truncation occur outside the directory's mutex, just like do_unlinkat() does. Signed-off-by:

Clean-up: Re-order the display of IP address and client ID to be consistent with other _cb_ tracepoints. Signed-off-by:

Chuck Lever authored
Clean up: These are noise in properly working systems. If you really need to observe the operation of the callback mechanism, use the sunrpc:rpc\* tracepoints along with the workqueue tracepoints. Signed-off-by:

Record a tracepoint event when the server performs a callback probe. This event can be enabled as a group with other nfsd_cb tracepoints. Signed-off-by:

Chuck Lever authored
Renamed so it can be enabled as a set with the other nfsd_cb_ tracepoints. And, consistent with those tracepoints, report the address of the client, the client ID the server has given it, and the state ID being recalled. Signed-off-by:

Record the arguments of CB_OFFLOAD callbacks so we can better observe asynchronous copy-offload behavior. For example: nfsd-995 [008] 7721.934222: nfsd_cb_offload: addr=192.168.2.51:0 client 6092a47c:35a43fc1 fh_hash=0x8739113a count=116528 status=0 Signed-off-by: -

When the server kicks off a CB_LM_NOTIFY callback, record its arguments so we can better observe asynchronous locking behavior. For example: nfsd-998 [002] 1471.705873: nfsd_cb_notify_lock: addr=192.168.2.51:0 client 6092a47c:35a43fc1 fh_hash=0x8950b23a Signed-off-by: -
