Subject: fsnotify: add flags to fsnotify_mark_entries
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=098cf2fc77ee190c92bf9d08d69a13305f2487ec;p=linux-beck.git

fsnotify: add flags to fsnotify_mark_entries

To differentiate between inode and vfsmount (or other future) types of
marks we add a flags field and set the inode bit on inode marks (the only
currently supported type of mark)
