From 86f35f34f419f6eaff53b25f463c13f72186b103 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Mon, 10 Oct 2011 10:42:59 -0700 Subject: [PATCH] Export symbols for the VFS API Export all symbols already marked extern in the zfs_vfsops.h header. Several non-static symbols have also been added to the header and exportewd. This allows external modules to more easily create and manipulate properly created ZFS filesystem type datasets. Rename zfsvfs_teardown() to zfs_sb_teardown and export it. This is done simply for consistency with the rest of the code base. All other zfsvfs_* functions have already been renamed.
