From c0111c44174a82f81c89ea79e70f2e95ba42c73f Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Mon, 21 Mar 2022 13:48:42 +0800 Subject: btrfs: simplify parameters of submit_read_repair() and rename Cleanup the function submit_read_repair() by: - Remove the fixed argument submit_bio_hook() The function is only called on buffered data read path, so the @submit_bio_hook argument is always btrfs_submit_data_bio(). Since it's fixed, then there is no need to pass that argument at all. - Rename the function to submit_data_read_repair() Just to be more explicit on all the 3 things, data, read and repair.
