🌈 scsi_intern...block_nowait(9) — the Kernel API Manual page bestie 🌈

🎀 NAME 🎀

scsi_internal_device_unblock_nowait — resume a device after a block request. 🫶

✨ SYNOPSIS ✨

int scsi_internal_device_unblock_nowait (struct scsi_device *sdev , enum
       scsi_device_state new_state );

🫶 ARGUMENTS 🫶

• sdev — device to resume. 💖
• new_state — state to set the device to after unblocking. ✨

💖 DESCRIPTION 💖

Okay so this one restarts the device queue for a previously suspended SCSI device. It does not sleep. 🛌🚫

It returns zero if successful or a negative error code upon failure. 💅

🧚 NOTES 🧚

This routine transitions the device to the SDEV_RUNNING state or to one of the offline states — and that transition must be a legal transition — allowing the midlayer to goose the queue for this device. 👑🐔

It’s giving “wake up bestie, but like, legally.” No cap. 🌸
