The 5.4 kernel has been released
Linus has released the 5.4 kernel.
"Not a lot happened this last week, which is just how I like
it". Significant features in this release include
the haltpoll
CPU governor,
the iocost (formerly io.weight) I/O
controller,
the EROFS filesystem,
an implementation of the exFAT filesystem
that may yet be superseded by a better version,
the fs-verity file integrity mechanism,
support for the BPF
compile once, run everywhere mechanism,
the dm-clone
device mapper target,
the virtiofs
filesystem,
kernel lockdown support (at last),
kernel symbol namespaces, and a new
random-number generator meant to solve the
early-boot entropy problem.
See the KernelNewbies 5.4
page for a lot more details.
