From 31dd8c81ddfa142dab53a0837eed88e8febe7b1e Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Tue, 30 May 2023 09:45:28 +0800 Subject: [PATCH] btrfs: use the same uptodate variable for end_bio_extent_readpage() In function end_bio_extent_readpage() we call endio_readpage_release_extent() to unlock the extent io tree. However we pass PageUptodate(page) as @uptodate parameter for it, while for previous end_page_read() call, we use a dedicated @uptodate local variable. This is not a big deal, as even for subpage cases, either the bio only covers part of the page, then the @uptodate is always false, and the subpage ranges can still be merged. But for the sake of consistency, always use @uptodate variable when possible.
