The patch titled
drivers/scsi: fix proc_scsi_write to return "length" on success with remove-single-device case
has been added to the -mm tree. Its filename is
drivers-scsi-fix-proc_scsi_write-to-return-length-on.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
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.
