* GFS2: Minor improvements to comments and documentationBob Peterson2018-04-121-2/+3
| | | | | | | This patch simply fixes some comments and the gfs2-glocks.txt file: Places where i_rwsem was called i_mutex, and adding i_rw_mutex. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
* gfs2: Remove gl_spin defineAndreas Gruenbacher2015-10-291-3/+3
| | | | | | | | | | Commit e66cf161 replaced the gl_spin spinlock in struct gfs2_glock with a gl_lockref lockref and defined gl_spin as gl_lockref.lock (the spinlock in gl_lockref). Remove that define to make the references to gl_lockref.lock more obvious. Signed-off-by: Andreas Gruenbacher <andreas.gruenbacher@gmail.com> Signed-off-by: Bob Peterson <rpeterso@redhat.com>
