[Ocfs2-tools-devel] [PATCH 1/2] fiemap: Add new extent flag FIEMAP_EXTENT_SHARED

[Sunil Mushran]

Mainline Linux commit 8c0414cd524e9f1c483ffb3ff1c2d860f5c567c8

Some filesystems may allow multiple files to point to a particular
extent.  This patch adds flag FIEMAP_EXTENT_SHARED to denote extents
that are shared with other inodes.
