Subject: [PATCH] btrfs: remove trivial nowait check
Date: Sat, 1 Feb 2020 11:51:33 +0800 [thread overview]
Message-ID: <1580529093-26170-1-git-send-email-qiwuchen55@gmail.com> (raw)
From: chenqiwu <chenqiwu@xiaomi.com>
Remove trivial nowait check for btrfs_file_write_iter(),
since buffered writes will return -EINVAL if IOCB_NOWAIT
passed in the follow-up function generic_write_checks().
