The inode is considered revalidated when we've checked the value of the

Merge tag 'nfs-for-5.13-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client updates from Trond Myklebust:
"Highlights include:

Stable fixes:

- Add validation of the UDP retrans parameter to prevent shift
out-of-bounds

- Don't discard pNFS layout segments that are marked for return

Bugfixes:

- Fix a NULL dereference crash in xprt_complete_bc_request() when the
NFSv4.1 server misbehaves.

- Fix the handling of NFS READDIR cookie verifiers

- Sundry fixes to ensure attribute revalidation works correctly when
the server does not return post-op attributes.

- nfs4_bitmask_adjust() must not change the server global bitmasks

- Fix major timeout handling in the RPC code.

- NFSv4.2 fallocate() fixes.

- Fix the NFSv4.2 SEEK_HOLE/SEEK_DATA end-of-file handling

- Copy offload attribute revalidation fixes

- Fix an incorrect filehandle size check in the pNFS flexfiles driver

- Fix several RDMA transport setup/teardown races

- Fix several RDMA queue wrapping issues

- Fix a misplaced memory read barrier in sunrpc's call_decode()

Features:

- Micro optimisation of the TCP transmission queue using TCP_CORK

- statx() performance improvements by further splitting up the
tracking of invalid cached file metadata.

- Support the NFSv4.2 'change_attr_type' attribute and use it to
optimise handling of change attribute updates"
