This commit introduces limited/recursive filesystem mounting by
leveraging the existing `zfs mount -a` codebase with minor additions
and modifications.
Now, when running `zfs mount <-a|-A> zpool/dataset`, the command will
mount all datasets that are the specified dataset itself or it's
children, provided they are available. In addition, `-A` flag will also
mount datasets with `canmount=noauto` property.
Changes in `zfs_main.c`:
- `HELP_MOUNT`
- Updated `usage()` message to reflect the changes.
- `get_all_state_t`
- Added `const char *ga_parent`; used to specify the parent dataset.
- `get_one_dataset()`
- Added a check; if `ga_parent` is set, skips any datasets that are
not `ga_parent` itself or it's children.
- `get_all_datasets()`
- Added `const char *parent` property; used to pass the parent dataset
to the `get_all_state_t` struct.
- `share_mount_state_t`
- Added `boolean_t sm_mount_noauto`; used to treat datasets with
`canmount=noauto` property as as if it were `canmount=on`.
- `share_mount_one()`;
- Added `boolean_t mount_noauto` property.
- Modified the 'noauto' check; when mounting datasets,
if `mount_noauto` is true, treat the mount as if `canmount=on` or
`explicit` is `B_TRUE`.
- `share_mount_one_cb()`
- Updated `share_mount_one()` call to include the new property,
passes the value of `sm_mount_noauto`.
- `share_mount()`
- Changed `do_all` from `int` to `boolean_t`
- Added `boolean_t do_noauto` property; used for mounting datasets
with `canmount=noauto` as `canmount=on`.
- Added the `-A` flag; when used sets `do_noauto` to `B_TRUE`.
- Updated argument check; displaies the correct error messages.
- Limited the usage of `<-a|-A> filesystem` to `zfs mount` only
- Added a check; to validate that the specified filesystem is indeed a
valid ZFS filesystem.
- Updated `get_all_datasets()` call to include the new property,
passes the value of `filesystem`.
- Added `share_mount_state.sm_mount_noauto`; the `share_mount_state_t`
has a new member, uses value of `do_noauto`
- Updated `share_mount_one()` call to include the new property,
passes the value `B_FALSE`.
