Subject: [PATCHv4 1/6] ext4: Add IOMAP_F_MERGED for non-extent based mapping
Date: Thu, 27 Feb 2020 16:40:22 +0530 [thread overview]
Message-ID: <8bffe1aef219916d3962faffd2e75cd7e06060c2.1582800839.git.riteshh@linux.ibm.com> (raw)
In-Reply-To: <cover.1582800839.git.riteshh@linux.ibm.com>
IOMAP_F_MERGED needs to be set in case of non-extent based mapping.
This is needed in later patches for conversion of ext4_fiemap to use iomap.
