[PATCH 1/1] f2fs: merge equivalent flags F2FS_GET_BLOCK_[READ|DIO]

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

 



From: Qiuyang Sun <sunqiuyang@xxxxxxxxxx>

Currently, the two flags F2FS_GET_BLOCK_[READ|DIO] are totally equivalent
and can be used interchangably in all scenarios they are involved in. This
patch deletes F2FS_GET_BLOCK_READ and uses F2FS_GET_BLOCK_DIO instead.
