Initially I started moving the dm-kcopyd interface to the block layer as a generic interface. Once I dig deeper in dm-kcopyd code, I figured that dm-kcopyd is tightly coupled with dm_io() To move dm-kcopyd to block layer, it would also require dm_io code to be moved to block layer. It would cause

[RFC PATCH v5 2/4] block: add simple copy support

2021-02-19 Thread SelvaKumar S
Add new BLKCOPY ioctl that offloads copying of one or more sources ranges to a destination in the device. Accepts a 'copy_range' structure that contains destination (in sectors), no of sources and pointer to the array of source ranges. Each source range is represented by 'range_entry' that contains
