If anyone has any objections, please let me know. ------------------ From: Yongpeng Yang [ Upstream commit 68a0178981a0f493295afa29f8880246e561494c ] When `fileinfo->fi_flags` does not have the `FIEMAP_FLAG_SYNC` bit set and inline data has not been persisted yet, the physical address of the extent is calculated incorrectly for unwritten inline inodes. root@vm:/mnt/f2fs# dd if=/dev/zero of=data.3k bs=3k count=1 root@vm:/mnt/f2fs# f2fs_io fiemap 0 100 data.3k Fiemap: offset = 0 len = 100 logical addr. physical addr. length flags 0 0000000000000000 00000ffffffff16c 0000000000000c00 00000301 This patch fixes the issue by checking if the inode's address is valid. If the inline inode is unwritten, set the physical address to 0 and mark the extent with `FIEMAP_EXTENT_UNKNOWN | FIEMAP_EXTENT_DELALLOC` flags.
