Subject: [f2fs-dev] [PATCH v2] f2fs: clean up f2fs_may_encrypt()
Date: Sat, 21 Mar 2020 20:19:33 +0800 [thread overview]
Message-ID: <20200321121933.22297-1-chao@kernel.org> (raw)
From: Chao Yu <yuchao0@huawei.com>
Merge below two conditions into f2fs_may_encrypt() for cleanup
- IS_ENCRYPTED()
- DUMMY_ENCRYPTION_ENABLED()
Check IS_ENCRYPTED(inode) condition in f2fs_init_inode_metadata()
is enough since we have already set encrypt flag in f2fs_new_inode().
Signed-off-by: Chao Yu <yuchao0@huawei.com>
---
v2:
- remove unneeded check condition in f2fs_init_inode_metadata() suggested
by Eric.
