[PATCH 4.19 222/323] ext4: rename journal_dev to s_journal_dev inside ext4_sb_info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Chunguang Xu <brookxu@xxxxxxxxxxx>

[ Upstream commit ee7ed3aa0f08621dbf897d2a98dc6f2c7e7d0335 ]

Rename journal_dev to s_journal_dev inside ext4_sb_info, keep
the naming rules consistent with other variables, which is
convenient for code reading and writing.
