[PATCH v2] mm, memory-failure: clarify error message

From: Jane Chu
Date: Mon May 20 2019 - 21:54:45 EST


Some user who install SIGBUS handler that does longjmp out
therefore keeping the process alive is confused by the error
message
"[188988.765862] Memory failure: 0x1840200: Killing
cellsrv:33395 due to hardware memory corruption"
Slightly modify the error message to improve clarity.
