Potential deadlock when lazytime-enabled mounted ploop is running on top of a fuse-based vStorage.
There is a possible deadlock if a lazytime-enabled mounted ploop is running on top of vStorage. This tweak provides the ability to disable default lazytime mount option for ext4 mounts. For technical reasons this tweak is united with the oom_dump_tasks sysctl. You should use this sysctl in the following way: "echo 0 > /proc/sys/vm/oom_dump_tasks" - disable lazytime default and oom tasks dumping; "echo 1 > /proc/sys/vm/oom_dump_tasks" - disable lazytime default, enable oom tasks dumping; "echo 2 > /proc/sys/vm/oom_dump_tasks" - enable lazytime default, disable oom tasks dumping; "echo 3 > /proc/sys/vm/oom_dump_tasks" - enable lazytime default and oom tasks dumping.
