Konstantin Belousov 8742817ba6 FFS extattr: fix handling of the tail ... There are three issues with change that stopped truncating ea area before write, and resulted in possible zero tail in the ea area: - Truncate to zero checked i_ea_len after the reference was dropped, making the last drop effectively truncate to zero length always. - Loop to fill uio for zeroing specified too large length, that triggered assert in normal situation. - Integrity check could trip over the tail, instead we must allow partial header or header with zero length, and clamp ea image in memory at it.
