[sheepdog] segfault in aio_read_response under write-heavy load

["Dvořák, Jan"]

Hi again,

qemu segfaults on us in sheepdog block driver.

(gdb) bt
#0  aio_read_response (opaque=0x0) at block/sheepdog.c:784
#1  0x0000555555619a0a in coroutine_trampoline (i0=<optimized out>,
i1=<optimize
d out>) at coroutine-ucontext.c:129
#2  0x00007ffff27eaef0 in ?? () from /lib64/libc.so.6
#3  0x00007fffffffcfc0 in ?? ()
#4  0x0000000000000000 in ?? ()

Can you help us out?

Best regards,
