Hello, I've been looking into the problem so far, may I ask why EXT4_STATE_MAY_INLINE_DATA isn't supposed to be set when the inode has inline data ? In context such as ext4_conver_inline_data(), the code there implies it is possible for an inode to have both EXT4_INODE_INLINE_DATA set and EXT4_STATE_MAY_INLINE_DATA set isn't it ? or my understanding is wrong, please correct me, I woud love to learn. Best regards, I Hsin Cheng.
