3.3 release announcement
warned developers that he would be taking a bit of time off during the
merge window; that did indeed happen over the last week. Still, he managed
to pull some 4,000 changesets since last week's
. Some of the more significant changes merged in the last week
- The PowerPC has gained a new firmware-assisted dump facility for the
quick capture and analysis of crash dumps.
- The GFS2 filesystem now supports the FITRIM ioctl()
command which can be used to send discard requests to the underlying
- The prctl() system call has a new option called
PR_SET_CHILD_SUBREAPER. Marking a process this way will
cause any orphan descendant processes to be reparented to the marked
process rather than to the init process. There is a
corresponding PR_GET_CHILD_SUBREAPER option as well.
- The Microblaze architecture now has high memory support.
- The ext4 "noacl" and "noattr" mount options have been marked
deprecated with an eye toward removal in the near future. Without
these options, it will not be possible to disable ACL and extended
attribute support. No other filesystem allows that support to be
disabled. The "journal=update" and "resize" mount options have been
removed entirely. On the other hand, plans to remove the "bsd_df",
"minix_df", "grpid" and "nogrpid" options have been dropped in
response to complaints from users.
- New hardware support includes:
Changes visible to kernel developers include:
Also worthy of note is that there has been a vast amount of work done in
the ARM architecture tree; the process of consolidating and cleaning up the
ARM code continues at a high rate.
The 3.4 merge window would normally be expected to end around
April 2. When he announced his vacation, Linus said that he would
extend the merge window for a bit if necessary - though he warned that he
would still only consider pull requests received during the window.
Whether that will happen remains to be seen; either way, next week's Kernel
Page will summarize the last new features merged for 3.4.
