Mariusz Zaborski a57d3d45d6 Add option for forcible unmounting dataset while receiving snapshot. ... Currently when the dataset is in use we can't receive snapshots. zfs send test/1@asd | zfs recv -FM test/2 cannot unmount '/test/2': Device busy This commits add option 'M' which attempts to forcibly unmount the dataset. Thanks to this we can enforce receiving snapshots in a single step. Note that this functionality is not supported on Linux because the VFS will prevent active mounted filesystems from being unmounted, even with the force option. This is the intended VFS behavior. Test cases were added to verify the expected behavior based on the platform.
