From 019e93516dcfc98efda51ccb8f7e0e758fda8ded Mon Sep 17 00:00:00 2001 From: "John L. Hammond" Date: Wed, 30 Mar 2016 19:48:35 -0400 Subject: [PATCH] staging/lustre/lmv: remove lmv_init_{lock,unlock}() In struct lmv_obd rename the init_mutex member to lmv_init_mutex. Remove the compat macros lmv_init_{lock,unlock}() and use mutex_{lock,unlock}(&lmv->lmv_init_mutex) instead. Signed-off-by: John L.
