From 5bcbc20e6442a32daf48971070e2f02a4bf524d2 Mon Sep 17 00:00:00 2001 From: Luo Jiaxing Date: Mon, 20 Jan 2020 20:22:34 +0800 Subject: [PATCH 042/108] scsi: hisi_sas: Modify the file permissions of trigger_dump to write only mainline inclusion from mainline-v5.6-rc1 commit 3cd2f3c35d29a50947a975feffdcbe2d6a2418c0 category: feature bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EKNE 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.
