XFS fatal asserts

configname: CONFIG_XFS_ASSERT_FATAL

Linux Kernel Configuration
└─>File systems
└─>XFS fatal asserts
In linux kernel since version 4.2 (release Date: 2015-08-30)  
Set the default DEBUG mode ASSERT failure behavior.

Say Y here to cause DEBUG mode ASSERT failures to result in fatal
errors that BUG() the kernel by default. If you say N, ASSERT failures
result in warnings.

This behavior can be modified at runtime via sysfs.
