[PATCH] fs/resctrl: avoid redundant call to strlen() in schemata_list_add()

Posted by Dmitry Antipov 3 months, 2 weeks ago

Since 'snprintf()' returns the number of characters emitted and an
overflow case is handled explicitly, an extra call to 'strlen()' in
'schemata_list_add()' may be dropped. Compile tested only.
