* Disable unused pathname::pn_path* (unneeded in Linux)Tomohiro Kusumi2019-07-151-0/+2
| | | | | | | | | | | | | | | | struct pathname is originally from Solaris VFS, and it has been used in ZoL to merely call VOP from Linux VFS interface without API change, therefore pathname::pn_path* are unused and unneeded. Technically, struct pathname is a wrapper for C string in ZoL. Saves stack a bit on lookup and unlink. (#if0'd members instead of removing since comments refer to them.)

* Add pn_alloc()/pn_free() functionsBrian Behlendorf2016-04-211-0/+70
In order to remove the HAVE_PN_UTILS wrappers the pn_alloc() and pn_free() functions must be implemented. The existing illumos implementation were used for this purpose. The `flags` argument which was used in places wrapped by the HAVE_PN_UTILS condition has beed added back to zfs_remove() and zfs_link() functions. This removes a small point of divergence between the ZoL code and upstream. Signed-off-by: Brian Behlendorf <[email protected]> Closes #4522
