The 4.5 kernel has been released
Linus has released the 4.5 kernel.
"So this is later on a Sunday than my usual schedule, because I just
couldn't make up my mind whether I should do another rc8 or not, and
kept just waffling about it. In the end, I obviously decided not to,
but it could have gone either way."
Some of the headline features from the development cycle are
dm-verity forward error
correction,
optional mandatory locking,
the new copy_file_range() system
call,
the SOCK_DESTROY operation,
another set of persistent-memory
improvements,
extended address-space layout randomization
on 32-bit systems,
the MADV_FREE option for
madvise(),
the UBSAN checker tool,
some extensions to
epoll_wait(),
project quotas for the ext4 filesystem,
and more.
