Subject: Re: math_state_restore and kernel_fpu_end disable interrupts?

THANK YOU!
I've been having a problem with ext4 metadata checksums, which use SSE
for large blocks, and traced it to kernel_fpu_end() disabling interrupts,
but had paused to debug this (I assumed well-tested) piece of kernel
code before pushing it harder.
(Search October-December LKML archives for "3.11.4: kernel BUG at
fs/buffer.c:1268".")
No, I'm pretty sure it's a real bug. At least, it's biting me on the
ass.
