fsnotify: pass flags argument to fsnotify_alloc_group()
[ Upstream commit 867a448d587e7fa845bceaf4ee1c632448f2a9fa ]
Add flags argument to fsnotify_alloc_group(), define and use the flag
FSNOTIFY_GROUP_USER in inotify and fanotify instead of the helper
fsnotify_alloc_user_group() to indicate user allocation.
Although the flag FSNOTIFY_GROUP_USER is currently not used after group
allocation, we store the flags argument in the group struct for future
use of other group flags.
