Changes from 1.3.26 to 1.3.27

These changes are archived on ftp.crynwr.com:pub/kchanges and http://www.crynwr.com/kchanges. I cannot answer questions about Linux -- I merely summarize the kernel patches after reading them. I try to make them useful to everyone, but kernel hackers should take them with a grain of salt and read the patches themselves. The patch file is patch-1.3.27.gz

These are from Linus:

It's a bird..

It's a plane..

No, it's KernelMan, faster than a speeding bullet, to your rescue. Doing new kernel versions in under 5 seconds flat..

[ Actually, it's been more than 24 hours, so I'm allowed ]

1.3.27 is available at the normal kernel sites (and mirrors, although it is conceivable that mirror sites haven't even caught up with 1.3.26 yet). The 1.3.27 kernel should fix the Oops messages at login if you used tcsh: it's a different fix than the one I sent out earlier, as I decided that I used the wrong approach at first.

[ "Technical" digression: the original patch continued to see the page fault counters as a part of the memory management information, which doesn't necessarily make sense. The faults were due to the memory management information having been free'd earlier, and no longer available at the time a process did a "wait4()". The 1.3.27 fix is essentially just realizing that the page fault counters don't count memory management things as much as events that occur in a thread, and as such the counters should be thread-specific rather than shared across all threads sharing a common memory map. ]

Anyway, that's one large reason to upgrade to 1.3.27 (if you haven't even upgraded to 1.3.26: shame on you, you lazy bum!). There are a few other reasons:

Eh, that's it, I guess. No 300 million dollar unveiling event for this kernel, I'm afraid, but you're still supposed to think of this as the "happening of the century" (at least until the next kernel comes along).

Oh, and this is another kernel in that great and venerable "BugFree(tm)" series of kernels. So be not afraid of bugs, but go out in the streets and deliver this message of joy to the masses.
