[LU-3709] Coordinator follow-on patche: code cleaning

Wed, 5 Aug 2020 13:32:56 +0000

When the cdt main thread will be landing some cross-component code cleaning needs to be done:

replace hai_zero() by hai_first()
display policy in /proc must be: policy1 [policy2] policy3
replace use of cfs_list_XXX by kernel functions, avoid use of list_entry() in list_XXX loop
remove extra parenthesis in if tests in HSM mdt files
"find" functions like mdt_hsm_get_md_hsm() or cdt_find_request_nolock() must return NULL if not found in place of ERR_PTR(-ENOENT)
clean 2 err msg in mdt_hsm_cdt_agent.c
styles in lmv_obd.c (from ~~LU-3365~~)
err code printed 2 times in mdt_hsm_cdt_agent.c

It will be safer to wait for sanity-hsm landing before landing these patches so maloo will validate them on the full HSM stack

I will prepare the patch
