Subject: Doubt on mmc erase command
Date: Tue, 10 Feb 2015 22:00:43 +0530 [thread overview]
Message-ID: <54DA3233.2090701@gmail.com> (raw)
Hello,
I'm trying to send ERASE Command to the emmc by deleting a file on one
of the emmc partitions and then doing a sync, But I'm noticing that even
this will not issue the erase command to emmc.
I did trace the code on, from where this erase command is issued, but my
trace ended at an ioctl call "do_vfs_ioctl()" more specific
"SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned
long, arg)" system call definition does a call to do_vfs_ioctl.
Please help me understand how to initiate this from userspace.
