Hi,

Is there any patch to correct libata working with ioctl()?

For example:

.~. # hdparm -t /dev/hda /dev/sda
/dev/hda:
Timing buffered disk reads: 174 MB in 3.03 seconds = 57.36 MB/sec
/dev/sda:
Timing buffered disk reads: 152 MB in 3.03 seconds = 50.11 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
.~. #

I can attach addition: dmesg, kernel.config, lspci, etc...

take care.

Probably hdparm is not the right software for this test, so sorry for bother
;-)

libata works fine with ioctl(2).

Arbitrary command execution is only supported in libata-dev tree for now.
