NFS: Clean up O_DIRECT request allocation

2023-02-14T19:22:33+00:00

Rather than adjusting the index+offset after the call to
nfs_create_request(), add a function nfs_page_create_from_page() that
takes an offset.

NFS: Convert buffered reads to use folios

2023-02-14T19:22:32+00:00

Perform a largely mechanical conversion of references to struct page and
page-specific functions to use the folio equivalents.

Note that the fscache functionality remains untouched. Instead we just
pass in the folio page. This should be OK, as long as we use order 0
folios together with fscache.

NFS: Add a helper to convert a struct nfs_page into an inode

2023-02-14T19:22:32+00:00

Replace all the open coded calls to page_file_mapping(req->wb_page)->host.

NFS: Improve write error tracing

2022-08-09T18:11:34+00:00

Don't leak request pointers, but use the "device:inode" labelling that
is used by all the other trace points. Furthermore, replace use of page
indexes with an offset, again in order to align behaviour with other
NFS trace points.

pNFS/flexfiles: Fix array overflow when flexfiles mirroring is enabled

2020-11-30T15:52:22+00:00

If the flexfiles mirroring is enabled, then the read code expects to be
able to set pgio->pg_mirror_idx to point to the data server that is
being used for this particular read. However it does not change the
pg_mirror_count because we only need to send a single read.

NFS: Try to join page groups before an O_DIRECT retransmission

2020-04-01T17:37:57+00:00

If we have to retransmit requests, try to join their page groups
first.

NFS: Refactor nfs_lock_and_join_requests()

2020-04-01T17:37:56+00:00

Refactor nfs_lock_and_join_requests() in order to separate out the
subrequest merging into its own function nfs_lock_and_join_group()
that can be used by O_DIRECT.

NFS: Clean up nfs_lock_and_join_requests()

2020-04-01T17:37:56+00:00

Clean up nfs_lock_and_join_requests() to simplify the calculation
of the range covered by the page group, taking into account the
presence of mirrors.
