The 4.0 kernel has been released
Linus has released the 4.0 kernel right on
schedule. "Feature-wise, 4.0 doesn't have all that much
special. Much have been made of the new kernel patching infrastructure, but
realistically, that not only wasn't the reason for the version number
change, we've had much bigger changes in other versions. So this is very
much a 'solid code progress' release." Beyond the (incomplete)
live-patching mechanism, this release includes the removal of the
remap_file_pages() system call, improved persistent memory support, the lazytime mount option, and the
kernel address sanitizer.
