Steven Whitehouse a2242db090 [GFS2] Speed up scanning of glocks ... I noticed the gfs2_scand seemed to be taking a lot of CPU, so in order to cut that down a bit, here is a patch. Firstly the type of a glock is a constant during its lifetime, so that its possible to check this without needing locking. I've moved the (common) case of testing for an inode glock outside of the glmutex lock. Also there was a mutex left over from when the glock cache was master of the inode cache. That isn't required any more so I've removed that too. There is probably scope for further speed ups in the future in this area.
