| |
I am removing the attached patch from libata-dev.git, as it does not justify the maintenance burden at the present time. The reasons it sat in libata-dev rather than go upstream are discussed at the top of the patch.
If anyone feels strongly about this ioctl, take it upon yourself to research the patch fully, address the concerns, and present an updated solution.
The patch will be archived forever at http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/archive/2.6.12-rc5-git8-ioctl-get-identity.patch.bz2
For inclusion,
a) should determine if need for ioctl justifies maintenance
b) should address Bart Z's concerns: * it is not complete HDIO_GET_IDENTIFY implementation (applications may assume otherwise) * you may need to add byte-swapping of the fields in the future (currently it is fine) * same info is available via pass-thru inteface

[PATCH] libata-scsi: get-identity ioctl support
This patch adds support for transfering drive informations via the hd_driveid structure to the hdparm utility. At the moment, only cylinders, sectors, heads, model and firmware version are transfered.
