Jan Kara 8edc6e1688 fanotify: fix notification of groups with inode & mount marks
fsnotify() needs to merge inode and mount marks lists when notifying
groups about events so that ignore masks from inode marks are reflected
in mount mark notifications and groups are notified in proper order
(according to priorities).

Currently the sorting of the lists done by fsnotify_add_inode_mark() /
fsnotify_add_vfsmount_mark() and fsnotify() differed which resulted
ignore masks not being used in some cases.

Fix the problem by always using the same comparison function when
sorting / merging the mark lists.

Thanks to Heinrich Schuchardt for improvements of my patch.
