[ Upstream commit e0462f91d24756916fded4313d508e0fc52f39c9 ]
According to Amir:
"FS_IN_IGNORED is completely internal to inotify and there is no need to set it in i_fsnotify_mask at all, so if we remove the bit from the output of inotify_arg_to_mask() no functionality will change and we will be able to overload the event bit for FS_ERROR."
This is done in preparation to overload FS_ERROR with the notification mechanism in fanotify.
