It's not, it keeps space in inode page only if inode is created when inline_xattr option is set. What I comment and suggest for MAX_FAST_SYMLINK_SIZE is wrong, sorry about that.
We'd better set max size of fast symlink according to inline_xattr flag:
static inline unsigned int max_fast_symlink_size(struct inode *inode) { return sizeof(__le32) * addrs_per_inode(F2FS_I(inode)); }
How do you think?
Thanks,
