Merge branch 'liblockdep-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux into core/urgent
Pull liblockdep fixes from Sasha Levin: " 1. There was a build breakage caused by marking a function 'asmlinkage' in lockdep.h. Fix that by ignoring asmlinkage and visible annotations. 2. Josh Boyer mentioned that Fedora would like to include liblockdep as a package, so we had to fix our versioning methods from being dumb and pointless to something actually usable. So now liblockdep.so tracks the kernel version which makes lives of distro folks much easier. " Signed-off-by: Ingo Molnar <mingo@kernel.org>
