The old scrub code has different entrance to verify the content, and since we have removed the writeback path, now we can start removing the re-check part, including: - scrub_recover structure - scrub_sector::recover member - function scrub_setup_recheck_block() - function scrub_recheck_block() - function scrub_recheck_block_checksum() - function scrub_repair_block_group_good_copy() - function scrub_repair_sector_from_good_copy() - function scrub_is_page_on_raid56() - function full_stripe_lock() - function search_full_stripe_lock() - function get_full_stripe_logical() - function insert_full_stripe_lock() - function lock_full_stripe() - function unlock_full_stripe() - btrfs_block_group::full_stripe_locks_root member - btrfs_full_stripe_locks_tree structure This infrastructure is to ensure RAID56 scrub is properly handling recovery and P/Q scrub correctly. This is no longer needed, before P/Q scrub we will wait for all the involved data stripes to be scrubbed first, and RAID56 code has internal lock to ensure no race in the same full stripe. - function scrub_print_warning() - function scrub_get_recover() - function scrub_put_recover() - function scrub_handle_errored_block() - function scrub_setup_recheck_block() - function scrub_bio_wait_endio() - function scrub_submit_raid56_bio_wait() - function scrub_recheck_block_on_raid56() - function scrub_recheck_block() - function scrub_recheck_block_checksum() - function scrub_repair_block_from_good_copy() - function scrub_repair_sector_from_good_copy() And two more functions exported temporarily for later cleanup: - alloc_scrub_sector() - alloc_scrub_block() Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
