[PATCH v2 0/3] Update fanotify man pages for NFSD filecache backports

[PATCH v2 0/3] Update fanotify man pages for NFSD filecache backports

[cel]

From: Chuck Lever <chuck.lever@oracle.com>

I backported a number of NFSD-related fixes to v5.15 and v5.10 LTS
kernels. The backports include some changes to the fanotify API
which need to be documented.

Changes since v1:
- Amir added a few items to the original list of updates

Chuck Lever (3):
  fanotify_mark(2): Support for FA_ flags has been backported to LTS
    kernels
  fanotify_init(2): Support for FA_ flags has been backported to LTS
    kernels
  fanotify(7): Document changes backported to LTS kernels
