2016-07-24pNFS: Clear the layout metadata if the server changed the layout stateidTrond Myklebust
If the server changed the layout stateid's "other" field, then we should treat the old layout as being completely gone. In that case, we want to clear the metadata such as scheduled layoutreturns. Do this by calling pnfs_mark_layout_stateid_invalid(). Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

2016-07-24NFS: pnfs_mark_matching_lsegs_return() should match the layout sequence idTrond Myklebust
When determining which layout segments to return, we do want pnfs_mark_matching_lsegs_return to check that they match the layout sequence id. This ensures that we don't waste time if the server is replaying a layout recall that has already been satisfied. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
2016-07-24pNFS: Do not set plh_return_seq for non-callback related layoutreturnsTrond Myklebust

2016-07-24pNFS: Ensure layoutreturn acts as a completion for layout callbacksTrond Myklebust
When we return NFS_OK to the CB_LAYOUTRECALL, we are required to send a layoutreturn that "completes" that layout recall request, using the correct stateid. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
2016-07-24pNFS: Fix CB_LAYOUTRECALL stateid verificationTrond Myklebust
We want to evaluate in this order: If the client holds no layout for this inode, then return NFS4ERR_NOMATCHING_LAYOUT; it probably forgot the layout. If the client finds the inode among the list of layouts, but the corresponding stateid has not yet been initialised, then return NFS4ERR_DELAY to ask the server to retry once the outstanding LAYOUTGET is complete. If the current layout stateid's "other" field does not match the recalled stateid, return NFS4ERR_BAD_STATEID. If already processing a layout recall with a newer stateid, return NFS4ERR_OLD_STATEID. This can only happens for servers that are non-compliant with the NFSv4.1 protocol. If already processing a layout recall with an older stateid, return NFS4ERR_DELAY to ask the server to retry once the outstanding LAYOUTRETURN is complete. Again, this is technically incompliant with the NFSv4.1 protocol. If the current layout sequence id is newer than the recalled stateid's sequence id, return NFS4ERR_OLD_STATEID. This too implies protocol non-compliance. If the current layout sequence id is older than the recalled stateid's sequence id+1, return NFS4ERR_DELAY.

2016-07-24pNFS: Always update the layout barrier seqid on LAYOUTGETTrond Myklebust
Currently, pnfs_set_layout_stateid() will update the layout sequence id barrier only if the stateid itself is newer than the current layout stateid. However in a situation where multiple LAYOUTGET calls and a LAYOUTRETURN raced, it is entirely possible for one of the LAYOUTGET to set the current stateid to something newer than the LAYOUTRETURN that needs to set the barrier. The fix is to allow the "update_barrier" flag to force a check as to whether or not the barrier needs to be updated. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
2016-07-24pNFS: Always update the layout stateid if NFS_LAYOUT_INVALID_STID is setTrond Myklebust

2016-07-24nfit: do an ARS scrub on hitting a latent media errorVishal Verma
When a latent (unknown to 'badblocks') error is encountered, it will trigger a machine check exception. On a system with machine check recovery, this will only SIGBUS the process(es) which had the bad page mapped (as opposed to a kernel panic on platforms without machine check recovery features). In the former case, we want to trigger a full rescan of that nvdimm bus. This will allow any additional, new errors to be captured in the block devices' badblocks lists, and offending operations on them can be trapped early, avoiding machine checks. This is done by registering a callback function with the x86_mce_decoder_chain and calling the new ars_rescan functionality with the address in the mce notificatiion. Cc: Rafael J.

On Marvell mv88f6180 with pin control driver one can not use multi purpose pins 35 through 44.

2016-07-23nfit, libnvdimm: allow an ARS scrub to be triggered on demandVishal Verma
Normally, an ARS (Address Range Scrub) only happens at boot/initialization time. There can however arise situations where a bus-wide rescan is needed - notably, in the case of discovering a latent media error, we should do a full rescan to figure out what other sectors are bad, and thus potentially avoid triggering an mce on them in the future. Also provide a sysfs trigger to start a bus-wide scrub. Cc: Rafael J.
