In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to check readonly condition correctly
With below case, it can mount multi-device image w/ rw option, however one of secondary device is set as ro, later update will cause panic, so let's introduce f2fsdevisreadonly(), and check multi-devices rw status in f2fsremount() w/ it in order to avoid such inconsistent mount status.
