mtd: Unconditionally update ->fail_addr and ->addr in part_erase()

2018-03-15T17:22:26Z

->fail_addr and ->addr can be updated no matter the result of parent->_erase(), we just need to remove the code doing the same thing in mtd_erase_callback() to avoid adjusting those fields twice. Note that this can be done because all MTD users have been converted to not pass an erase_info->callback() and are thus only taking the ->addr_fail and ->addr fields into account after part_erase() has returned. While we're at it, get rid of the erase_info->mtd field which was only needed to let mtd_erase_callback() get the partition device back.

mtd: Stop assuming mtd_erase() is asynchronous

2018-03-15T17:21:07Z

None of the mtd->_erase() implementations work in an asynchronous manner, so let's simplify MTD users that call mtd_erase(). All they need to do is check the value returned by mtd_erase() and assume that != 0 means failure. Signed-off-by: Boris Brezillon Reviewed-by: Richard Weinberger

mtd: tests: Replace timeval with ktime_t

2015-10-26T20:23:47Z

Changes the 32-bit time type timeval to the 64-bit time type ktime_t, since 32-bit systems using struct timeval will break in the year 2038. Correspondingly change do_gettimeofday() to ktime_get() since ktime_get returns a ktime_t, but do_gettimeofday returns a struct timeval.Here, ktime_get() is used instead of ktime_get_real() since ktime_get() uses monotonic clock.

mtd: Make MTD tests cancelable

2015-04-06T01:12:53Z

I always go nuts when I start an MTD test on a slow device and have to wait forever until it finishes. From the debug output I already know what the issue is but I have to wait or reset the board hard. Resetting is often not an option (remote access, you don't want lose the current state, etc...). The solution is easy, check for pending signals at key positions in the code. Using that one can even stop a test by pressing CTRL-C as insmod/modprobe have SIGINT pending.

mtd: tests: fix integer overflow issues

2014-08-19T18:53:08Z

These multiplications are done with 32-bit arithmetic, then converted to 64-bit. We should widen the integers first to prevent overflow. This could be a problem for large (>4GB) MTD's. Detected by Coverity. Signed-off-by: Brian Norris Cc: Akinobu Mita

mtd: tests: incorporate error message for mtdtest_write()

2013-08-30T20:36:06Z

All callers of mtdtest_write() print the same error message on failure. This incorporates the error message to mtdtest_write() and removes them from the callers. Signed-off-by: Akinobu Mita Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: tests: rename sources in order to link a helper object

2013-08-30T20:34:06Z

Each mtd test module have a single source whose name is the same as the module name. In order to link a single object including helper functions to every test module, this rename these sources to the different names.
