xfs: Output warning message when discard option was enabled even though the device does not support discard
In order to using discard function, it is necessary that not only xfs
is mounted with discard option, but also the discard function is
supported by the device. Current code doesn't output any message when
users mount with discard option on unsupported device, so it is
difficult to notice that it was not enabled actually.
This patch adds the warning message to notice that discard option is
not enabled due to unsupported device when the filesystem is mounted.
Changes in v2 (Suggested by Brian Foster):
- Move the unsupported device check into xfs_fs_fill_super().
- Clear the discard flag when device is unsupported.
