What it is

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 <[email protected]> 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.
