Rename 'btrfs_io_stripe::is_scrub' to 'rst_search_commit_root'. While 'is_scrub' describes the state of the io_stripe (it is a stripe submitted by scrub) it does not describe the purpose, namely looking at the commit root when searching RAID stripe-tree entries. Renaming the stripe to rst_search_commit_root describes this purpose. Reviewed-by:

This just creates unnecessary noise and doesn't provide any insights into debugging RAID stripe-tree related issues. Reviewed-by:

Add a comment to document the complicated locked_page unlock logic in cow_file_range_inline. The specifically tricky part is that a caller just up the stack converts ret == 0 to ret == 1 and then another caller far up the callstack handles ret == 1 as a success, AND returns without cleanup in that case, both of which "feel" unnatural and led to the original bug. Try to document that somewhat specific callstack logic here to explain the weird un-setting of locked_folio on success. Reviewed-by:

When iterating the chunk maps when a device replace finishes we are doing a full rbtree search for each chunk map, which is not the most efficient thing to do, wasting CPU time. As we are holding a write lock on the tree during the whole iteration, we can simply start from the first node in the tree and then move to the next chunk map by doing a rb_next() call - the only exception is when we need to reschedule, in which case we have to do a full rbtree search since we dropped the write lock and the tree may have changed (chunk maps may have been removed and the tree got rebalanced). So just do that. Signed-off-by:

At the end of a device replace we must go over all the chunk maps and update their stripes to point to the target device instead of the source device. We iterate over the chunk maps while holding a write lock and we never reschedule, which can result in monopolizing a CPU for too long and blocking readers for too long (it's a rw lock, non-blocking). So improve on this by rescheduling if necessary. This is safe because at this point we are holding the chunk mutex, which means no new chunks can be allocated and therefore we don't risk missing a new chunk map that covers a range behind the last one we processed before rescheduling.

Instead of getting a page and using that to clear dirty for io, use the folio helper and use the appropriate folio functions. Signed-off-by:

We only use a page to copy in the data for the inline extent. Use a folio for this instead. Signed-off-by:
