[lustre-devel] [PATCH 013/622] lustre: obdclass: fix llog_cat_cleanup() usage on Client

[James Simmons]

From: Bruno Faccini <bruno.faccini at intel.com>

With patch/commit 3a83b4b9 for LU-5195, LLOG code has been
strengthen against catalog inconsistency by detecting a
referenced plain LLOG is missing and by clearing its
associated entry by calling llog_cat_cleanup(), which now
needs to handle the case where it is also executed on a Client
(ie, cathandle->lgh_obj == NULL) and thus must not attempt to
update on-disk catalog.
