[PATCH v3 05/12] ext4: passing block allocation information to ext4_es_insert_extent()

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

 



From: Zhang Yi <yi.zhang@xxxxxxxxxx>

Just pass the block allocation flag to ext4_es_insert_extent() when we
replacing a current extent after an actually block allocation or extent
status conversion, this flag will be used by later changes.
