The current implementation directly monitor /proc/self/mountinfo and /run/mount/utab files. It's really not optimal because utab file is private libmount stuff without any official guaranteed semantic. The libmount since v2.26 provides API to monitor mount kernel & userspace changes. This patch replaces the current implementation with libmount based solution. Now the manager.h includes <libmount.h>, so $MOUNT_CFLAGS has been necessary to add to many tests CFLAGS. Note that mnt_monitor_event_cleanup() in v2.26 is broken, so the patch uses mnt_monitor_next_change(). It's exactly the same solution which uses the current libmount HEAD (mnt_monitor_event_cleanup() is API shorcut only).

Could you rebase and force-push this one to trigger Semaphore? I'd lilke to know whether the build deps are satisfied on their side. |
