  cifs: Do not leak EDEADLK to dgetents64 for
STATUS_USER_SESSION_DELETED (2021-08-25 16:08:38 -0500)

----------------------------------------------------------------
11 cifs/smb3 client fixes:
- mostly restructuring to allow disabling less secure algorithms (this
will allow eventual removing rc4 and md4 from general use in the
kernel)
- 4 fixes, including 2 for stable
- enable r/w support with fscache and cifs.ko

Am working on a larger set of changes (the usual ... multichannel,
auth and signing improvements), but wanted to get these in earlier to
reduce chance of merge conflicts
later in the merge window.
