This function is intended to allow looking up the dev_t of a block device based on a name string before the root file systems is mounted and thus the normal path based lookup is available. Unfortunately a few years ago it managed to get exported and used in non-init contexts, leading to the something looking like a path name also beeing lookuped up by a different and potential dangerous algorithm. This series does a fair amount of refactoring and finally ends up with the renamed and improved name_to_dev_t only beeing available for the early init code again. The series is against Jens' for-6.5/block tree but probably applies against current mainline just fine as well. A git tree is also available here: git://git.infradead.org/users/hch/block.git blk-init-cleanup Gitweb: http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/blk-init-cleanup Changes since v1: - really propagate the actual error in dm_get_device - improve the documentation in kernel-parameters.txt - spelling fixes Diffstat: ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
