Qu Wenruo dad7a67c2f btrfs: fix the error handling for submit_extent_page() for btrfs_do_readpage() ... commit 10f7f6f879 upstream. [BUG] Test case generic/475 have a very high chance (almost 100%) to hit a fs hang, where a data page will never be unlocked and hang all later operations. [CAUSE] In btrfs_do_readpage(), if we hit an error from submit_extent_page() we will try to do the cleanup for our current io range, and exit. This works fine for PAGE_SIZE == sectorsize cases, but not for subpage. For subpage btrfs_do_readpage() will lock the full page first, which can contain several different sectors and extents: btrfs_do_readpage() |- begin_page_read() | |- btrfs_subpage_start_reader(); | Now the page will have PAGE_SIZE / sectorsize reader pending, | and the page is locked. | |- end_page_read() for different branches | This function will reduce subpage readers, and when readers | reach 0, it will unlock the page. But when submit_extent_page() failed, we only cleanup the current io range, while the remaining io range will never be cleaned up, and the page remains locked forever. [FIX] Update the error handling of submit_extent_page() to cleanup all the remaining subpage range before exiting the loop. Please note that, now submit_extent_page() can only fail due to sanity check in alloc_new_bio(). Thus regular IO errors are impossible to trigger the error path.
