Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3cd2f3c35d29a50947a975feffdcbe2d6a2418c0

----------------------------------------------------------------------
|
|
|
|
The trigger_dump file is only used to manually trigger the dump, and did
|
|
not provide a read callback function for it, so its file permission
|
|
setting to 600 is wrong,and should be changed to 200.
