In this scenario, the next\ncall to ext4_write_begin() will not prepare the inline data xattr for\nwriting, but ext4_journalled_write_end() will incorrectly attempt to write\nto it, triggering a BUG_ON(pos + len > EXT4_I(inode)->i_inline_size) in\next4_write_inline_data() since i_inline_size was not expanded.\n\nFix this by ensuring that ext4_journalled_write_end() only calls\next4_write_inline_data_end() if the EXT4_STATE_MAY_INLINE_DATA flag is\nset, mirroring the behavior of ext4_write_end() and ext4_da_write_end()."
