Oh yeah. In that case, the memset thing I mentioned earlier might help.

Looks fine, thanks Jeff.

Introduce GFP_NOWAIT, as an alias for GFP_ATOMIC & ~__GFP_HIGH.
This also changes XFS, which is the only in-tree user of this idiom that I

Change memory hotplug to use GFP_NOWAIT instead of GFP_ATOMIC, so that it
will grab memory without sleeping, but doesn't try to use the emergency pools.

Then, when I use fread to read
my file into this buffer, if I read a small number of bytes, it
works.
However when I try to fread the entire file (38k), fread returns 0.
What's the break point between working and non-working?
It looks like it's on a page boundary. 4095 bytes is ok, 4096 i
