Fix this by zero-initializing the block.\n\nThis bug was introduced by commit 4ec17d688d74 (\"f2fs: avoid unneeded\ninitializing when converting inline dentry\"), which didn't consider the\nsecurity implications of leaking uninitialized memory to disk.\n\nThis was found by running xfstest generic/435 on a KMSAN-enabled kernel."
