I'm proposing this series as the first NFSD-related patchset to go
into v6.2 (for-next), though I haven't opened that yet.
For quite some time, we've been encouraged to disable filecache
garbage collection for NFSv4 files, and I think I found a surgical
way to do just that. That is presented in "NFSD: Add an NFSD_FILE_GC
flag to enable nfsd_file garbage collection".
To make that fit, I've dropped Jeff's fix for nfsd_file_close(), but
incorporated his proposed replacement logic into nfsd_file_put().
The justification for that can be found in the patch descriptions.
Jeff's other two patches are included here because I intend to get
them merged into v6.1 soon thus they will become part of the base
for NFSD for-next. For the moment I'm leaving out Fixes tags because
I'd like to see these get some testing before they are applied to
v6.0 -- and again, we're not yet 100% sure these fix a misbehavior
that has been hit in the field.
Comments and opinions are welcome.
