ata_scsi_dma_need_drain(9)

🦋 ata_scsi_dma_need_drain(9) 🦋

okay so bestie, welcome to the Kernel API Manual page for ata_scsi_dma_need_drain(9) — yes, the title is a whole mouthful, but we're gonna get through it together. 💖

✨ NAME ✨

• ata_scsi_dma_need_drain — Check whether data transfer may overflow.

🌸 SYNOPSIS 🌸

bool ata_scsi_dma_need_drain (struct request *rq );

🎀 ARGUMENTS 🎀

• rq — request to be checked. That's the whole assignment, bestie.

💅 DESCRIPTION 💅

okay so picture this: ATAPI commands which transfer variable length data to host might overflow due to application error or hardware bug. 😭 This function checks whether overflow should be drained and ignored for request.

LOCKING: None. No locks, no drama — it's giving zero locking. ✨

⭐ RETURN ⭐

Return line, verbatim: 1 if ; otherwise, 0. 💀 yes, exactly like that — semicolon and all. We're not inventing a condition, bestie. 😭
