next in thread | raw e-mail | index | archive | help
At some point between 42d088299c (4 May) and f0c9703301 (26 June), a
deadlock was introduced in ZFS. It is still present as of 9c2823bae9 (4
August) and is 100% reproducable just by starting poudriere bulk in a
16-core VM and waiting a few hours until deadlkres kicks in. In the
latest instance, deadlkres complained about a bash process:

zfs: Fix build on 32-bit platforms after most recent import.
=20=20=20=20=20=20=20=20
unsigned long is not a uint64_t on 32-bit platforms. The zfs.4
manpage documents this variable as a uint, and it is only compared
with other variables of type int, so uint_t makes more sense than
unsigned long.
=20=20=20=20=20=20=20=20
(I also wasn't sure if ULONG would work as a ZFS_MODULE_PARAM type
on other OS's)
