[PATCH v2 08/12] md/raid5: Refactor for loop in raid5_make_request() into while loop

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

 



The for loop with retry label can be more cleanly expressed as a while
loop by moving the logical_sector increment into the success path.

No functional changes intended.
