* fstrim: add --quiet option to suppress error messagesSami Kerola2019-05-071-1/+9
| | | | | | | | | | | | | When fstrim interacts with NTFS it result can be error reporting bad file descriptor. That seems to be a bug in NTFS. While waiting driver to get on top of the issue and be commonly available lets add to fstrim option to make it be more silent about errno 9 aka EBADF, Bad file descriptor.

* fstrim: trim also root FS on --fstabKarel Zak2018-12-101-1/+2
