ext4: implement FALLOC_FL_ZEROINIT_RANGEzero-initialize-pmem-5.16_2021-09-23
Implement this new fallocate mode so that persistent memory users can,
upon receipt of a pmem poison notification, cause the pmem to be
reinitialized to a known value (zero) and clear any hardware poison
state that might be lurking.
