From 8bdd5b60e0273e6682d5c269c70e6287ae60eb55 Mon Sep 17 00:00:00 2001 From: Wang Long Date: Sun, 20 May 2018 22:38:26 -0400 Subject: jbd2: remove NULL check before calling kmem_cache_destroy() The kmem_cache_destroy() function already checks for null pointers, so we can remove the check at the call site. This patch also sets jbd2_handle_cache and jbd2_inode_cache to be NULL after freeing them in jbd2_journal_destroy_handle_cache().
