From e0553a74adf1b1035e1ae25ca7feacacdeb93931 Mon Sep 17 00:00:00 2001 From: Olaf Faaland Date: Fri, 6 Nov 2015 09:38:27 -0800 Subject: [PATCH] Add lock types RW_NOLOCKDEP and MUTEX_NOLOCKDEP Both lock types were introduced in SPL to allow some locks to be taken/released with linux lockdep turned off. See SPL commit for details. Add the new lock types to zfs_context.h to allow user space compilation.
