From 7bb41db3ea160ea55cc46af07e45f7cb1e2968ba Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 21 Jun 2016 09:56:26 +1000 Subject: [PATCH] xfs: handle 64-bit length in xfs_iozero We'll want to use this code for large offsets now that we're skipping holes and unwritten extents efficiently. Also rename it to xfs_zero_range to be a bit more descriptive, and tell the caller if we actually did any zeroing.
