Linus Torvalds: Linux 2.5.56

By

Kernel.org
Mirrors

FullChangelog


Trying to make releases slightly more often and slightly smaller.

ACPI, USB, networking (mainly netfilter) updates. Some syscall path
updates and a thread bug in mm_release() that would miss updating the TID
and cause a few extra traps at exec time.

And a watchdog forward port from 2.4.x by DaveJ.

                        Linus
