. The shared pagetable code is back in. Seems to be stabilising.
If anyone has any weird problems, please see if a `patch -R -p1 <
shpte-ng.patch' fixes it up, thanks.
. There have been ongoing travails in the direct-io code since the
introduction of bio_add_page().
It was all turning into a bit of a pickle, so I got down and
rewrote the file-walk, assembly and BIO submission phase in a manner
which suits the bio_add_page() semantics. This version is, IMO,
significantly clearer. And it now runs the modified-for-O_DIRECT
fsx-linux code without going BUG.
This of course broke the allow-512-byte-alignment patch; that needs
to be redone.
. There is a series of debloat patches here. Expect to see the
kernel use 100k less memory on UP and 300k less on SMP.
Well, more accurately 10k * (NR_CPUS - number_of_cpus).
. A series of updates from Bill on the large page filesystem and shm
patches
. I'm carrying ninety five diffs here. People who send me patches
for integration: please, keep it as small as is practical, and not
trivial stuff. Thanks.
