Sarthak Kukreti 3a01c48e7a block: Don't invalidate pagecache for invalid falloc modes ... commit 1364a3c391 upstream. Only call truncate_bdev_range() if the fallocate mode is supported. This fixes a bug where data in the pagecache could be invalidated if the fallocate() was called on the block device with an invalid mode. Fixes: 25f4c41415 ("block: implement (some of) fallocate for block devices") Cc: stable@vger.kernel.org Reported-by: "Darrick J.
