Currently it was only doing it if we created the compression bios, otherwise it was depending on btrfs_submit_data_bio() to do the right thing. This creates the above problem, so fix up btrfs_submit_compressed_read() to always call bio_endio() in case of an error, and then simply return from btrfs_submit_data_bio() if we had to call btrfs_submit_compressed_read().</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>btrfs: do not double complete bio on errors during compressed reads</p> <p>I hit some weird panics while fixing up the error handling from btrfs_lookup_bio_sums().
