6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christoph Hellwig <hch@xxxxxx> [ Upstream commit 0ef2b9e698dbf9ba78f67952a747f35eb7060470 ] Make bio_is_zone_append globally available, because file systems need to use to check for a zone append bio in their end_io handlers to deal with the block layer emulation.
