When NFS requests are split into sub-requests, nfs_inode_remove_request
calls nfs_page_group_sync_on_bit to set PG_REMOVE on this sub-request and
only completes the head requests once PG_REMOVE is set on all requests.
This means that when nfs_lock_and_join_requests sees a PG_REMOVE bit, I/O
on the request is in progress and has partially completed. If such a
request is returned to nfs_try_to_update_request, it could be extended
with the newly dirtied region and I/O for the combined range will be
re-scheduled, leading to extra I/O.
Change the logic to instead restart the search for a request when any
PG_REMOVE bit is set, as the completion handler will remove the request
as soon as it can take the page group lock. This not only avoid
extending the I/O but also does the right thing for the callers that
want to cancel or flush the request.

nfs_folio_find_and_lock_request and the nfs_page_group_lock_head helper

But given that only the head request can be stashed in the folio private

Previously in order to mark the communication with the DS server,
we tried to use NFS_CS_DS in cl_flags. However, this flag would
only be saved for the DS server and in case where DS equals MDS,
the client would not find a matching nfs_client in nfs_match_client
that represents the MDS (but is also a DS).
Instead, don't rely on the NFS_CS_DS but instead use NFS_CS_PNFS.

Commit 6df25e5853 ("nfs: remove reliance on bdi congestion")
introduced NFS-private solution for limiting number of writes
outstanding against a particular server. Unlike previous bdi congestion
this algorithm actually works and limits number of outstanding writeback
pages to nfs_congestion_kb which scales with amount of client's memory
and is capped at 256 MB. As a result some workloads such as random
buffered writes over NFS got slower (from ~170 MB/s to ~126 MB/s). The
fio command to reproduce is:
fio --direct=0 --ioengine=sync --thread --invalidate=1 --group_reporting=1
--runtime=300 --fallocate=posix --ramp_time=10 --new_group --rw=randwrite
--size=64256m --numjobs=4 --bs=4k --fsync_on_close=1 --end_fsync=1
This happens because the client sends ~256 MB worth of dirty pages to
the server and any further background writeback request is ignored until
the number of writeback pages gets below the threshold of 192 MB. By the
time this happens and clients decides to trigger another round of
writeback, the server often has no pages to write and the disk is idle.
To fix this problem and make the client react faster to eased congestion
of the server by blocking waiting for congestion to resolve instead of
aborting writeback. This improves the random 4k buffered write
throughput to 184 MB/s.

But this isn't a fatal error if the subsequent device open is

always appears whether there is a problem or not.
Instead, generate less system journal noise by reporting an error
only when both open attempts fail. The new error message is more

This appears to be due to a race. bl_alloc_lseg() calls this:
561 static struct nfs4_deviceid_node *
562 bl_find_get_deviceid(struct nfs_server *server,
563 const struct nfs4_deviceid *id, const struct cred *cred,
564 gfp_t gfp_mask)
565 {
566 struct nfs4_deviceid_node *node;
567 unsigned long start, end;
568
569 retry:
570 node = nfs4_find_get_deviceid(server, id, cred, gfp_mask);
571 if (!node)
572 return ERR_PTR(-ENODEV);
nfs4_find_get_deviceid() does a lookup without the spin lock first.
If it can't find a matching deviceid, it creates a new device_info
(which calls bl_alloc_deviceid_node, and that registers the device's
PR key).
Then it takes the nfs4_deviceid_lock and looks up the deviceid again.
If it finds it this time, bl_find_get_deviceid() frees the spare
(new) device_info, which unregisters the PR key for the same device.
Any subsequent I/O from this client on that device gets EBADE.
The umount later unregisters the device's PR key again.
To prevent this problem, register the PR key after the deviceid_node
lookup.
