Hi,
Changes since v7:
- Switched from using SRCU to percpu_ref to interlock
nfsd_destroy_serv() and nfsd_open_local_fh().
- Dropped the "nfs/localio: use dedicated workqueues for filesystem
read and write" patch, will revisit if/when needed based on evidence
- Changed NFSD_MAY_LOCALIO from 0x800000 to 0x2000.
- Various renames in fs/nfsd/localio.c XDR code suggested by Chuck.
- Fixed localio_procedures1 and ARRAY_SIZE suggested by Neil.
- Fixed nfsd_uuid_is_local() to dereference nfsd_uuid within rcu
- Removed a few dprintk in fs/{nfs,nfsd}/localio.c
- Documentation improvements suggested by Jeff.
TODO:
- Must fix xfstests generic/355 (clear suid bit on write)
- Must fix localio's nfs_get_vfs_attr() to support NFS v4 same as is
done with nfsd4_change_attribute(). But first attempt to do so was
met with a crash due to the extra STATX_BTIME | STATX_CHANGE_COOKIE
being included in the request_mask passed to vfs_getattr().
All review and comments are welcome!
Thanks,
Mike
