 Specifies a colon-separated list of files in fstab or kernel mountinfo format. All missing or empty files are silently ignored. The evaluation of the _list_ stops after first non-empty file. For example:
 +
 *--listed-in /etc/fstab:/proc/self/mountinfo*.
++
+Filesystems with "X-fstrim.notrim" mount option in fstab are skipped.
 
 *-m, --minimum* _minimum-size_::
 Minimum contiguous free range to discard, in bytes. (This value is internally rounded up to a multiple of the filesystem block size.) Free ranges smaller than this will be ignored and *fstrim* will adjust the minimum if it's smaller than the device's minimum, and report that (fstrim_range.minlen) back to userspace. By increasing this value, the *fstrim* operation will complete more quickly for filesystems with badly fragmented freespace, although not all blocks will be discarded. The default value is zero, discarding every free block.
