Hi,
I have a storage filter driver. In this driver among other things I am monitoring IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES for the SSD trim commands. Now I am working with a Toshiba tablet which uses a eMMC storage device. According to Wikipedia “eMMC 4.5 further defines a ‘discard’ sub-operation that more closely matches ATA TRIM in that the contents of discarded blocks can be considered indeterminate (i.e., ‘don’t care’)”, I would like to catch this command too. And I was wondering if anyone knows the appropriate IOCTL for this command.
Thanks
Rehan
