Linux Kernel 3.12 Released

Linus Torvalds has announced the release of Linux Kernel 3.12: I was vacillating whether to do an rc8 or just cut the final 3.12, but since the biggest reason to *not* do a final release was not so much the state of the code, as simply the fact that I’ll be traveling with very bad internet connection next week, I didn’t really want to delay the release. Sure, we had a number of driver reverts, and there was an annoying auto-NUMA memory corruption fix series, but none of it was really worth delaying 3.12 for. But the fact that I’m going to be (effectively) off-line next week means that I’m *not* opening the merge window for 3.13 yet – since I won’t have the bandwidth to really do merges anyway. That doesn’t mean that you can’t send me pull request for the merge window early, of course – maintainers can […]

Linux Kernel 3.10 Released

Linus Torvalds has announced the release of Linux Kernel 3.10: So I delayed this by a day, considering whether to do another -rc, but decided that there wasn’t enough upside. Sure, it hasn’t been as quiet as I’d like, and we had this long discussion about an inode list locking scalability issue over the last week or two, but in the end that issue turned out to not be new, and while we may end up back-porting the eventual resolution to 3.10, it wasn’t a reason to delay the release. Similarly, while I might wish for fewer pull requests during the late rc’s (and particularly the ones that came in Friday evening -inconvenient for a weekend release), at some point delaying things doesn’t really help things, and just makes the pent up demand for the next merge window worse. In other words, I could really have gone either way, but […]

Linux 3.9 Release

Linus Torvalds has announced the release of Linux Kernel 3.9: So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn’t  actually want to do a final release last week. Please don’t do that. Anyway. Whatever the reason, this week has been very quiet, which makes me much more comfortable doing the final 3.9 release, so I guess the last -rc8 ended up working. Because not only aren’t there very many commits here, even the ones that made it really are tiny and not pretty obscure and not very interesting. Also, this obviously means that the merge window is open. I won’t be merging anything today, but if […]

Linux 3.8 Release

Linus Torvalds has announced the release of Linux Kernel 3.8: The release got delayed a couple of days because I was waiting for confirmation of a small patch, but hey, we could also say that it was all intentional, and that this is the special “Presidents’ Day Release”. It sounds more planned that way, no? Anyway, the really good news is that things calmed down a lot on the last week. There are noticeably fewer commits, and they are also all quite small. The few commits with more than just a couple of lines tend to be due to a couple of reverts, and two architecture patches where some identifiers got renamed (tile), or some defines got moved from the uapi file to a private header (x86). And there’s one radeon patch that uses a helper function instead of reading bytes directly. And even those “bigger” patches weren’t really that […]

Linux 3.7 Release

Linus Torvalds has announced the release of Linux Kernel 3.7: Whee. After an extra rc release, 3.7 is now out. After a few more trials at fixing things, in the end we ended up reverting the kswapd changes that caused problems. And with the extra rc, I had decided to risk doing the buffer.c cleanups that would otherwise have just been marked for stable during the next merge window, and had enough time to fix a few problems that people found there too. There’s also a fix for a SCSI driver bug that was exposed by the last-minute workqueue fixes in rc8. Other than that, there’s a few networking fixes, and some trivial fixes for sparc and MIPS. Anyway, it’s been a somewhat drawn out release despite the 3.7 merge window having otherwise appeared pretty straightforward, and none of the rc’s were all that big either. But we’re done, and […]

Linux 3.5 Release

Linus Torvalds has announced the release of Linux Kernel 3.5: Subject: Linux 3.5 released Ok, not a lot happened since -rc7. There’s a number of MIPS commits (for some reason MIPS has had a horrible track record with the -rc time schedule, I suspect I should just stop pulling late in the game), but most of the rest is pretty small. A couple of dm/md fixes, some gma500 work, make kgdb ‘dmesg’ command work again, some networking fixes, some xfs and cifs noise, yadda yadda. About 50% of the patch is actually the SPEAr clock name renaming that is just some search-and-replace. … Linux 3.4 brought updates to Btrfs file system, some new Intel, AMD and NVidia GPU drivers, X32 ABI, perf tool improvements and support for Yama security module and QNX6 file system. Linux 3.5 brings the following key changes: ext4 metadata checksums:  Ext4 has added the ability to […]

Linux 3.4 Release

Linus Torvalds has just announced the release of Linux Kernel 3.4 on the 20th of May: I just pushed out the 3.4 release. Nothing really exciting happened since -rc7, although the workaround for a linker bug on x86 is larger than I’d have liked at this stage, and sticks out like a sore thumb in the diffstat. That said, it’s not like even that patch was really all that scary. In fact, I think the 3.4 release cycle as a whole has been fairly calm. Sure, I always wish for the -rc’s to calm down more quickly than they ever seem to do, but I think on the whole we didn’t have any big disruptive events, which is just how I like it. Let’s hope the 3.5 merge window is a calm one too. Linus Linux 3.3 merged Android drivers to mainline, added further improvements to btrfs and ext-4 file […]

Linux 3.3 Release

Linux Torvalds announced the release of Linux Kernel 3.3 on the 18th of March: So after the extra -rc release last weekend, now the final 3.3 is out there in the usual locations. Things did indeed calm down during the last week, and the shortlog looks pretty boring. The diffstat from -rc7 is dominated by the arch/tile defconfig changes, the rest is pretty small, although there are changes spread out in various subsystems (drivers, filesystem, networking, perf tools). … And obviously, the 3.3 release means that the merge window for 3.4 is now open, although I may keep of pulling stuff for a day or so to encourage people to test the actual release. Linux 3.2 brought ext-4 and btrfs file system improvements, support for Qualcomm Hexagon processor, an improved profiling tool (perf top), and better CPU and network bandwidth management. Linux 3.3 brings the following key changes: Android merge: […]
