[PATCH] Free up page-private for compound pages
If we add a new flag so that we can distinguish between the
first page and the tail pages then we can avoid to use page-private
in the first page. page-private == page for the first page, so there
is no real information in there.
Freeing up
Unalias PG_tail for performance reasons
If PG_tail is an alias then we need to check PageCompound before PageTail.
This is particularly bad because the slab and others have to use these tests
in performance critical paths.
This patch uses one of the freed up software suspend flags that is
Hi,
How can I control the size of the block requests the sendfile() syscall
performs
against the disk?
I'm using sendfile (on a 2.6.18 kernel) to copy 1M file chunks into a
socket. The
socket send buffer size is 2MB, and I verify that its empty before
making the call.
Indeed, 1M chunk is

This implements granule page sized vmemmap support for IA64.
Christoph,
Your calculations here are all based on a granule size of 16M, but
it is possible to configure 64M granules.
With current sizeof(struct page) == 56, a 16M page will hold enough
page structures for about 4.5G of physical

We carefully set loglevel to 7, and print the sysrq messsage

the output as it sets it back before calling the handler,
rather than after.
Move the assignment down one line.

Why would the numbers be prone to change, any more than they are
already?

Because now 8250 ports can actually coexist with Zilog ports. Before my
fix, it was strictly one or the other.

Maybe a granule is not the right unit of allocation ... perhaps 4M
would work better (4M/56 ~= 75000 pages ~= 1.1G)? But if this is
too small, then a hard-coded 16M would be better than a granule,
because 64M is (IMHO)
