Hi,
the patch btrfs: properly set the termination value of ctx->pos in
readdir introduces a regression to me.
A lot of stuff runs in "endless" or long running loops.
An example strace looks like this:
msgsnd(0, {1,
"\3\0\0\0\247\r\0\0g8\0\0\0\0\0\0\0\0\0\0\345<\1\0\0\0\0\0\35\0\0\0"...}, 56,
0)

Hi Chris,
Which kernel are you running?

vanilla 3.8.3.
Ok, with the 3.9 merge window Josef changed how we do the reservations.
Are you able to try a slightly more experimental kernel?
any ideas what i can check? 3.9-rc3 gives me same results.

the second issue you're seeing was discussed here:

You can apply the patch I sent there meanwhile, but as Miao pointed
out, I will need to make a better patch (hope will do it soon,

Yes i will do so. Right now i was trying to compare discard with non

for i in `seq 0 1 1000`; do dd if=/dev/zero of=t_$i bs=4M count=1; rm
t_$i; done;

No problem.
Kernel trace:
Thats weird, sysrq+w should have a bunch of stacktraces but it's empty, so
unless theres a bug theres nothing blocked. Is the box actually hung or is it
just taking forever? Maybe try sysrq+w again to see if the one you pasted was
just a fluke? Thanks,
