The function read_extent_from_disk() is only a wrapper to read tree block. And read_extent_data() is just a while loop to eliminate short read caused by stripe boundary. In fact, a lot of call sites of read_extent_data() are either reading metadata (thus no possible short read) or doing extra loop by themselves. This patch will replace those two functions with read_data_from_disk(), making it the only entrance for data/metadata read. And update read_data_from_disk() to return the read bytes, so caller can do a simple while loop. For the few callers of read_extent_data(), open-code a small while loop for them. This will allow later RAID56 read repair using P/Q much easier. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |
