Linux 6.3 compat: idmapped mount API changes
Linux kernel 6.3 changed a bunch of APIs to use the dedicated idmap type for mounts (struct mnt_idmap), we need to detect these changes and make zfs work with the new APIs. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Youzhong Yang <[email protected]> Closes #14682
