From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chandan Rajendra Subject: [RFC PATCH] fiemap-tester.c: Do not error out when FIEMAP_EXTENT_NOT_ALIGNED is set and extent is aligned. Date: Wed, 15 Apr 2015 18:59:53 +0530 Message-ID: <1429104593-24136-1-git-send-email-chandan@linux.vnet.ibm.com> Cc: Chandan Rajendra , linux-fsdevel@vger.kernel.org, chandan@mykolab.com To: fstests@vger.kernel.org Return-path: Sender: fstests-owner@vger.kernel.org List-Id: linux-fsdevel.vger.kernel.org >>From Linux kernel's Documentation/filesystems/fiemap.txt, * FIEMAP_EXTENT_NOT_ALIGNED Extent offsets and length are not guaranteed to be block aligned. So this means that FIEMAP_EXTENT_NOT_ALIGNED is just a hint that indicates that the extent range could possibly be out of alignment w.r.t to the filesystem's blocksize. It should still be possible for fiemap ioctl to return extents with FIEMAP_EXTENT_NOT_ALIGNED flag set (e.g. Inline extents) but which have blocksize aligned ranges.
