The patch titled
Subject: fs, fanotify: add @mflags field to fanotify output
has been removed from the -mm tree. Its filename was
fs-fanotify-add-mflags-field-to-fanotify-output.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Cyrill Gorcunov <gorcunov@xxxxxxxxxx>
Subject: fs, fanotify: add @mflags field to fanotify output
The kernel keeps FAN_MARK_IGNORED_SURV_MODIFY bit separately from
fsnotify_mark::mask|ignored_mask thus put it in @mflags (mark flags) field
so the user-space reader will be able to detect if such bit were used on
mark creation procedure.
