[PATCH v5 18/18] fs: enable pre-content events on supported file systems

Josef Bacik
2024-09-04T20:29:45Z

Now that all the code has been added for pre-content events, and the
various file systems that need the page fault hooks for fsnotify have
been updated, add FS_ALLOW_HSM to the currently tested file systems.
