2017-06-08mtd: subpagetest: fix wrong written check in function write_eraseblock2Xiaolei Li
Write size in function write_eraseblock2 is subpgsize * k. It is wrong to check whether written is equal to subpgsize after each mtd_write.

2015-04-05mtd: Make MTD tests cancelableRichard Weinberger
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.

2014-08-19mtd: tests: fix integer overflow issuesBrian Norris
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.

2013-10-27mtd: nand: add a helper to detect the nand typeHuang Shijie
This helper detects that whether the mtd's type is nand type. Now, it's clear that the MTD_NANDFLASH stands for SLC nand only. So use the mtd_type_is_nand() to replace the old check method to do the nand type (include the SLC and MLC) check.

2013-08-30mtd: tests: rename sources in order to link a helper objectAkinobu Mita
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.
