Description

In the Linux kernel, the following vulnerability has been resolved: iomap: add a separate bio_set for iomap_split_ioend iomap_split_ioend can split bios that already come from iomap_ioend_bioset and thus deadlock when the bioset is exhausted. Add a separate bio_set to avoid this deadlock. Christian Brauner <brauner@kernel.org> says: Mark iomap_ioend_split_bioset static as it is only used in ioend.c, fixing the sparse warning reported by the kernel test robot.
