[PATCH v3] decode mtd ioctls
Mike Frysinger
vapier at gentoo.org
Thu Apr 5 02:19:58 UTC 2012
I got tired of figuring out mtd structures (which show up a lot
in the embedded space), so add decoders for those ioctls.
* defs.h (mtd_ioctl): New prototype.
(print_loff_t): Likewise.
* io.c (print_loff_t): Delete static keyword
* ioctl.c (ioctl_decode): Call mtd_ioctl when code is 'M'.
* Makefile.am (strace_SOURCES): Add mtd.c.
* mtd.c: New file.
* linux/mtd-abi.h: New file.

v3
- include local copy of mtd-abi.h and use it when host is old
