Subject: xfs: evict CoW fork extents when performing finsert/fcollapse
From: Darrick J. Wong <[email protected]>
commit 3af423b03435c81036fa710623d3ae92fbe346a3 upstream.
When we perform an finsert/fcollapse operation, cancel all the CoW extents for the affected file offset range so that they don't end up pointing to the wrong blocks.
