[LTP] [PATCH 0/5] Fanotify tests for FAN_MARK_EVICTABLE

[Amir Goldstein]

Hi Petr,

FAN_MARK_EVICTABLE feature was merge in v5.19-rc1.

Here are the tests for it.

inotify12 is a test for an unrelated fix.

Note that fanotify23 is run on ext2.
That is because, I could not find a way to reliably evict
an inode on any filesystem and the rain dance I did with
vfs_cache_pressure and drop_caches works reliably with ext2
on my test setup.

If that turns out not to work on other systems, we will need
to re-think of a more aggressive way to force inode eviction.

Thanks,
Amir.
