NFSD: Replace the use of include/trace/misc/nfs.h

2026-10-05T01:15:29+00:00

fs/nfsd/trace.h includes include/trace/misc/nfs.h for
show_nfs4_seq4_status() and show_rca_mask(). That header pulls in
linux/nfs.h, so every NFSD translation unit that reads trace.h also
sees the NFS_OK, NFSERR_*, and file-type enumerators.

I'm about to switch fs/nfsd/nfserr.h to an xdrgen-generated header,
which defines enum nfsstat and enum ftype with those same names. Any
translation unit that includes both headers then fails to build with
enumerator redefinition errors.

To address this, stop including trace/misc/nfs.h in fs/nfsd/trace.h.

NFSD: Resolve the recall-any mask names in the trace format

2026-10-05T01:15:29+00:00

RCA4_TYPE_MASK_* are enum constants, so the preprocessor cannot fold
them into the print format that show_rca_mask() builds for the
nfsd_cb_recall_any event. Nothing declares an eval map for them
either, so trace_event_eval_update() has no substitution to apply at
module load, and the event's format file ships the enumerator names
verbatim. trace-cmd and perf cannot decode the bmval0 field.

Declare the eval maps for the nine mask bits show_rca_mask() decodes.
The format then carries the shift counts as integers, the same shape
the SUNRPC trace points already emit from their BIT() flag decoders.

NFS: Move definition of enum nfs3_stable_how

2026-10-05T01:15:29+00:00

Clean up: enum nfs3_stable_how was introduced in NFSv3. NFSv2 has no
stable_how on the wire; its write path passes NFS_FILE_SYNC only as
a placeholder that the protocol ignores. The stable_how constants
describe an NFSv3 wire value, so they belong in linux/nfs3.h.

NFSD: Remove NFSERR_EAGAIN

2026-01-02T18:43:41+00:00

I haven't found an NFSERR_EAGAIN in RFCs 1094, 1813, 7530, or 8881.
None of these RFCs have an NFS status code that match the numeric
value "11".

Based on the meaning of the EAGAIN errno, I presume the use of this
status in NFSD means NFS4ERR_DELAY. So replace the one usage of
nfserr_eagain, and remove it from NFSD's NFS status conversion
tables.

As far as I can tell, NFSERR_EAGAIN has existed since the pre-git
era, but was not actually used by any code until commit f4e44b393389
("NFSD: delay unmount source's export after inter-server copy
completed."), at which time it become possible for NFSD to return
a status code of 11 (which is not valid NFS protocol).

Fixes: f4e44b393389 ("NFSD: delay unmount source's export after inter-server copy completed.")

NFSD: filecache: add STATX_DIOALIGN and STATX_DIO_READ_ALIGN support

2025-09-30T20:10:05+00:00

Use STATX_DIOALIGN and STATX_DIO_READ_ALIGN to get DIO alignment
attributes from the underlying filesystem and store them in the
associated nfsd_file. This is done when the nfsd_file is first
opened for each regular file.
