Subject: [PATCH v2 08/10] syscalls/fanotify20: Test event after filesystem abort
Date:   Tue, 26 Oct 2021 15:42:37 -0300

This test monitors the error triggered after a file system abort.  It
works by forcing a remount with the option "abort".  This is an error
not related to a file so it is reported against the superblock with a
zero size fh.
