[Cluster-devel] [GFS2 PATCH] GFS2: Don't bother trying to add rgrps to the lru list

[Bob Peterson]

Hi,

This patch removes a call to gfs2_glock_add_to_lru from function
gfs2_clear_rgrpd, which is called when GFS2 is removing all the
rgrps from memory. The call is just a waste of time because as soon
as it adds it to the lru_list, the subsequent call to gfs2_glock_put
takes it back off again. It doesn't make sense for the rgrps to ever
be on the lru list anyway because gfs2_rgrp_glops doesn't even have
the GLOF_LRU bit set (by design).
