Subject: [PATCH] ext4: remove unneeded check of nr_to_submit
Date: Thu, 16 Mar 2023 16:48:31 -0400 [thread overview]
Message-ID: <20230316204831.2472537-1-trix@redhat.com> (raw)
cppcheck reports
fs/ext4/page-io.c:516:51: style:
Condition 'nr_to_submit' is always true [knownConditionTrueFalse]
if (fscrypt_inode_uses_fs_layer_crypto(inode) && nr_to_submit) {
^
This earlier check to bail, makes this check unncessary
/* Nothing to submit? Just unlock the page... */
if (!nr_to_submit)
return 0;
