Hi - I'm trying out btrfs again, and I see the same old bug in kernel 3.1.4
(Fedora 16, x86_64, dual-core), where after a few hours of writing, it
switches from writing with several threads to writing with one:
Ok, I'll try to reproduce this here. Could you please do a sysrq-t, I'd
like to see what the other delalloc-writers are doing.
I've attached sysrq-t. It looks like it might be truncated at the
beginning, however.
/var/log/messages may have the whole thing, please do check.
That was from /var/log/messages. I think it needs a longer log_buf_len.
Unfortunately the system hasn't come back from its reboot, so it will
have to wait until tomorrow when I can get to it physically.
