Subject: [PATCH] ext4: remove unused parameter biop in ext4_issue_discard()
Date: Mon, 26 Feb 2024 16:17:31 +0800 [thread overview]
Message-ID: <20240226081731.3224470-1-haowenchao2@huawei.com> (raw)
all caller of ext4_issue_discard() would set biop to NULL since
'commit 55cdd0af2bc5 ("ext4: get discard out of jbd2 commit kthread
contex")', it's unnecessary to keep this parameter any more.
