f2fs: fix to use inline space only if inline_xattr is enable
With below mkfs and mount option:
MKFS_OPTIONS -- -O extra_attr -O project_quota -O inode_checksum -O flexible_inline_xattr -O inode_crtime -f
MOUNT_OPTIONS -- -o noinline_xattr
We may miss xattr data with below testcase:
- mkdir dir
- setfattr -n "user.name" -v 0 dir
- for ((i = 0; i < 190; i++)) do touch dir/$i; done
- umount
- mount
- getfattr -n "user.name" dir
user.name: No such attribute
The root cause is that we persist xattr data into reserved inline xattr
space, even if inline_xattr is not enable in inline directory inode, after
inline dentry conversion, reserved space no longer exists, so that xattr
data missed.
Let's use inline xattr space only if inline_xattr flag is set on inode
to fix this iusse.
