File util-linux-fstrim-RO.patch of Package util-linux-systemd.31381

Subject: [PATCH] fstrim -a/-A: Skip read-only volumes

Calling TRIM on some read-only volumes can fail with:
fstrim: /win: FITRIM ioctl failed: Bad file descriptor

Skipping all read-only mounts seems to be safe and logical strategy.

Fixes opensuse#1106214.
