From 3f16ecd950e56d60a574f73af9538f6e24030f9a Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 8 Aug 2018 17:36:29 +0800 Subject: f2fs: fix to return success when trimming meta area generic/251 --- tests/generic/251.out 2016-05-03 20:20:11.381899000 +0800 QA output created by 251 Running the test: done. +fstrim: /mnt/scratch_f2fs: FITRIM ioctl failed: Invalid argument +fstrim: /mnt/scratch_f2fs: FITRIM ioctl failed: Invalid argument +fstrim: /mnt/scratch_f2fs: FITRIM ioctl failed: Invalid argument +fstrim: /mnt/scratch_f2fs: FITRIM ioctl failed: Invalid argument +fstrim: /mnt/scratch_f2fs: FITRIM ioctl failed: Invalid argument ... Ran: generic/251 Failures: generic/251 The reason is coverage of fstrim locates in meta area, previously we just return -EINVAL for such case, making generic/251 failed, to fix this problem, let's relieve restriction to return success with no block discarded.
