Dear Dan Carpenter, I know what you wrote, but before device is removed and freed memory automatically, programming pages may do many many times. Assume we erase and rewrite a large part of the flash, then spinand_program_page() might exhaust memory if memory is not large enough. In fact, OOM indeed occured when I tested programming multi-pages by mtd_debug tool. If OOM was not caused by devm_kzalloc() in spinand_program_page(), what may exhaust memory?
