NFS: Create a new nfs_alloc_fattr_with_label() function

2021-11-05T18:54:38+00:00

For creating fattrs with the label field already allocated for us. I
also update nfs_free_fattr() to free the label in the end.

NFS: Fix up commit deadlocks

2021-10-20T22:09:45+00:00

If O_DIRECT bumps the commit_info rpcs_out field, then that could lead
to fsync() hangs. The fix is to ensure that O_DIRECT calls
nfs_commit_end().

NFS: Further optimisations for 'ls -l'

2021-10-04T00:49:07+00:00

If a user is doing 'ls -l', we have a heuristic in GETATTR that tells
the readdir code to try to use READDIRPLUS in order to refresh the inode
attributes. In certain cirumstances, we also try to invalidate the
remaining directory entries in order to ensure this refresh.

If there are multiple readers of the directory, we probably should avoid
invalidating the page cache, since the heuristic breaks down in that
situation anyway.

NFS: Fix up nfs_ctx_key_to_expire()

2021-10-04T00:49:05+00:00

If the cached credential exists but doesn't have any expiration callback
then exit early.
Fix up atomicity issues when replacing the credential with a new one
since the existing code could lead to refcount leaks.
