Alan Cox: Announcing Linux 2.4.5-ac1

Cox writes, “In terms of going through the code audit almost all the sound drivers
still
need fixing to lock against format changes during a read/write. Poll
creating
and starting a buffer as write does and also mmap during write, write
during
an mmap.”

“This is the merge with Linus 2.4.5 tree. Its probably primarily of
interest
to folks who want to review the merge – in paticular on the VM side of
things.”
