[PATCH 07/12] iomap: zero newly allocated mapped blocks

2019-10-15 Thread Christoph Hellwig
File systems like gfs2 don't support delayed allocations or unwritten extents and thus allocate normal mapped blocks to fill holes. To cover the case of such file systems allocating new blocks to fill holes also zero out mapped blocks with the new flag. Signed-off-by: Christoph Hellwig
