dio_bio_reap

函数名称：A really large O_DIRECT read or write can generate a lot of BIOs. So* to keep the memory consumption sane we periodically reap any completed BIOs* during the BIO generation phase.* This also helps to limit the peak amount of pinned userspace memory.

函数原型：static inline int dio_bio_reap(struct dio *dio, struct dio_submit *sdio)

返回类型：int

参数：

类型	参数	名称
struct dio *	dio
struct dio_submit *	sdio

566

ret等于0

568

如果ate limit reaping 自加大于等于64则

569

当singly linked via bi_private 循环

574

spin_lock_irqsave( & protects BIO fields below , flags)

575

bio等于singly linked via bi_private

576

singly linked via bi_private 等于bi_private

577

spin_unlock_irqrestore( & protects BIO fields below , flags)

578

ret2等于blk_status_to_errno(dio_bio_complete(dio, bio))

579

如果ret恒等于0则ret等于ret2

582

ate limit reaping 等于0

584

返回:ret
