Oh, missed your note on commit:
[ pvorel: move test into staging ]

If I'd known, I might have remembered to remind you ;-)

fanotify23 and fanotify10 both added tests for
FAN_MARK_EVICTABLE at the same time.

But since then there were two attempts to improve the reliability
of fanotify10:

48cfd7a99 syscalls/fanotify10: Make evictable marks test more reliable
4fefdf340 fanotify10: Make evictable marks tests more reliable

I wonder if fanotify23's reliability did not come up so far because
1. It was in staging list
2. It has this hack:
       /* Shrinkers on other fs do not work reliably enough to
guarantee mark eviction on drop_caches */
       .dev_fs_type = "ext2",

I guess we will know soon ...

Thanks,
Amir.
