2015-12-28NFSv4: List stateid information in the callback tracepointsTrond Myklebust1-2/+67
The stateid is extremely valuable when debugging. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
2015-12-28pNFS: Modify pnfs_update_layout tracepoints to use layout stateidTrond Myklebust1-6/+17
Instead of displaying a layout segment pointer in these tracepoints, let's use the layout stateid, now that Olga gave us a set of tools for displaying them. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
2015-12-28nfs: add new tracepoint for pnfs_update_layoutJeff Layton1-0/+56
pnfs_update_layout is really the "nexus" of layout handling. If it returns NULL then we end up going through the MDS. This patch adds some tracepoints to that function that allow us to determine the cause when we end up going through the MDS unexpectedly.

2015-12-28Adding stateid information to tracepointsOlga Kornievskaia1-25/+230
Operations to which stateid information is added: close, delegreturn, open, read, setattr, layoutget, layoutcommit, test_stateid, write, lock, locku, lockt Format is "stateid=<seqid>:<crc32 hash stateid.other>", also "openstateid=", "layoutstateid=", and "lockstateid=" for open_file, layoutget, set_lock tracepoints. New function is added to internal.h, nfs_stateid_hash(), to compute the hash trace_nfs4_setattr() is moved from nfs4_do_setattr() to _nfs4_do_setattr() to get access to stateid. trace_nfs4_setattr and trace_nfs4_delegreturn are changed from INODE_EVENT to new event type, INODE_STATEID_EVENT which is same as INODE_EVENT but adds stateid information for locking tracepoints, moved trace_nfs4_set_lock() into _nfs4_do_setlk() to get access to stateid information, and removed trace_nfs4_lock_reclaim(), trace_nfs4_lock_expired() as they call into _nfs4_do_setlk() and both were previously same LOCK_EVENT type.

2015-10-06NFS: Fix a tracepoint NULL-pointer dereferenceAnna Schumaker1-1/+1
Running xfstest generic/013 with the tracepoint nfs:nfs4_open_file enabled produces a NULL-pointer dereference when calculating fileid and filehandle of the opened file. Fix this by checking if state is NULL before trying to use the inode pointer.

2014-06-24nfs: merge nfs_pgio_data into _headerWeston Andros Adamson1-14/+14
struct nfs_pgio_data only exists as a member of nfs_pgio_header, but is passed around everywhere, because there used to be multiple _data structs per _header. Many of these functions then use the _data to find a pointer to the _header. This patch cleans this up by merging the nfs_pgio_data structure into nfs_pgio_header and passing nfs_pgio_header around instead.
