btw, there's an additional patch I have queued up that might have an
effect. please test the attached (which is my 2.6.25 queue).

Yep - I've made a quick short test - and it looks promising - so far I
can not see the leak
with your additional patch.
But I still have get my busy loop problem. Though now it's sometime
stack-back-traced on the leaveq - maybe this instruction might cause
some problems ??
Before this patch - I've always got the back-trace at the point of
copy_user_generic_string -
now its slightly different -- and still applies when I run the second
dmsetup status - it unblocks the looped one)

[kvm-devel] Qemu-kvm is leaking my memory ???
Hello Recently I'm using qemu-kvm on fedora-rawhide box with my own kernels (with many debug options) I've noticed that over the time my memory seems to disappear somewhere. Here is my memory trace after boot and some time of work - thus memory should be populated.

Then before I rebooted the machine I've killed nearly all running task (i.e no Xserver, most of services turned of) MemTotal: 2007416 kB MemFree:652412 kB Buffers: 7 kB Cached: 607144 kB SwapCached: 0 kB Active: 571464 kB Inactive: 709796 kB SwapTotal: 0 kB SwapFree:0 kB Dirty: 0 kB Writeback: 0 kB AnonPages:6408 kB Mapped: 4844 kB Slab:52620 kB SReclaimable:32752 kB SUnreclaim: 19868 kB PageTables: 1468 kB NFS_Unstable:0 kB Bounce: 0 kB CommitLimit: 1003708 kB Committed_AS:33988 kB VmallocTotal: 34359738367 kB VmallocUsed: 68152 kB VmallocChunk: 34359668731 kB I've have expected much more free memory here and I definitely do not see how this could combine 2GB of my memory: 652412 + 7 + 607144 + 6408 + 4844 + 52620 + 32752 + 19868 + 1468 = 1447516 1.4GB so where is my 600MB piece of memory hiding ?
