From 694c793fc1ade0946149c5f8d43f71e0728c4e81 Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Fri, 18 Apr 2014 10:21:15 -0400 Subject: [PATCH] ext4: use truncate_pagecache() in collapse range We should be using truncate_pagecache() instead of truncate_pagecache_range() in the collapse range because we're truncating page cache from offset to the end of file. truncate_pagecache() also get rid of the private COWed pages from the range because we're going to shift the end of the file.
