It seems like usb-storage and aio are completely off in the weeds.
Ideas?
It seems usb-storage should remove some kmalloc and use mempool
() for
urb... Is someone working on this? And idea?
I think Pete said that we're supposed to be using GFP_NOIO in there.
We _are_ using it.
How admirably prompt.
Not that it'll help much: the VM calls throttle_vm_writeout() for
GFP_NOIO
and GFP_NOFS allocations, which is a bug. Because if the caller
holds
locks which prevent filesystem or IO progress, we deadlock.
I'll fix the VM if someone else fixes USB ;)
What else needs to be fixed?
Would be nice if someone can confirm that this fixes it:
Doesn't seem to help my problem in a quick test, will get more data
in the morning.
