[libvirt] [PATCH] cgroup: Add missing errno == ENOENT check in virCgroupRemoveRecursively

ENOENT happens normally when a subsystem is enabled with any other subsystems and the directory of the target group has already removed in a prior loop. In that case, the function should just return without leaving an error message. NB this is the same behavior as before introducing virCgroupRemoveRecursively. --- src/util/cgroup.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/src/util/cgroup.c b/src/util/cgroup.c index 62b1446..9fa64dc 100644 --- a/src/util/cgroup.c +++ b/src/util/cgroup.c @@ -616,6 +616,8 @@ static int virCgroupRemoveRecursively(char *grppath) grpdir = opendir(grppath); if (grpdir == NULL) { + if (errno == ENOENT) + return 0; VIR_ERROR(_("Unable to open %s (%d)"), grppath, errno); rc = -errno; return rc; -- 1.6.5.2
