[patch 01/20] drivers/scsi: fix proc_scsi_write to return "length" on success with remove-single-device case

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

 



From: Suzuki <suzuki@xxxxxxxxxx>

proc_scsi_write doesn't return the "length" upon successfully removing a
device; instead it returns 0.  This causes commands like "echo" to redo the
write(), which ends up in something like,

$ echo "scsi remove-single-device 0 0 3 0" > /proc/scsi/scsi
"-bash: echo: write error: No such device or address"

, even though the device was removed.
