Hi Amir,

This needs to be:
+				FSID_VAL_MEMBER(event_fid->fsid, 0),
+				FSID_VAL_MEMBER(event_fid->fsid, 1),

FSID_VAL_MEMBER() is a wrapper struct fanotify_event_info_fid, needed to fix
build on musl (and it shouldn't be used for struct event_t).

Also I got problems on FUSE:
safe_macros.c:754: INFO: Trying FUSE...
tst_test.c:1244: INFO: Timeout per run is 0h 05m 00s
fanotify16.c:112: INFO: Test #0: FAN_REPORT_FID with mark type: FAN_MARK_FILESYSTEM
fanotify16.c:138: BROK: fanotify_mark (3, FAN_MARK_ADD | FAN_MARK_FILESYSTEM, FAN_DIR_MODIFY, AT_FDCWD, 'fs_mnt') failed: ENODEV (19)
tst_device.c:373: INFO: umount('fs_mnt') failed with EBUSY, try  1...
tst_device.c:377: INFO: Likely gvfsd-trash is probing newly mounted fs, kill it to speed up tests.

Skipping FUSE fixes it:
.dev_fs_flags = TST_FS_SKIP_FUSE,

Kind regards,
Petr
