Kernel release status
Linus's BitKeeper tree contains some framebuffer fixes, more annotations of user-space pointers and makefile support for Linus's (still unreleased) kernel source analyzer, 48-bit IDE addressing support, a (hopefully) working IDE tagged command queueing implementation, the BIO "walking" API, more devfs cleanups (devfs_register() is gone), the USB "gadget" subsystem, a wireless networking update (and quite a bit of networking work in general), dynamic block I/O request allocation, a fair amount of SCSI cleanup work, a generic x86 subarchitecture, a number of TTY layer cleanups, a USB update, an IA-64 update, and a vast number of other fixes.
The current stable kernel is 2.4.20; Marcelo released the second 2.4.21 release candidate on May 8. This patch fixes the aic7xxx problems (though not entirely to the satisfaction of the aic7xxx maintainer) and adds a fair number of other small fixes.
