Michael Hudson-Doyle	1f4e90d468	linux: return UNSUPPORTED from tst-mount if entering mount namespace fails ...

Also change the test to remove the unnecessary fork. Reviewed-by: Carlos O'Donell <carlos@redhat.com>	2022-07-19 06:55:49 +12:00
Adhemerval Zanella	af1aa36c61	linux: Add mount_setattr ... It was added on Linux 5.12 (2a1867219c7b27f928e2545782b86daaf9ad50bd) to allow change the properties of a mount or a mount tree using file descriptors which the new mount api is based on. Checked on x86_64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>	2022-07-05 10:08:48 -03:00
Adhemerval Zanella	c3b02b6567	linux: Add tst-mount to check for Linux new mount API ... The new mount API was added on Linux 5.2 with six new syscalls: fsopen, fsconfig, fsmount, move_mount, fspick, and open_tree. The new test verifies minimal functionality along with error paths for specific arguments and their corner cases. Checked on x86_64-linux-gnu.
