Darrick J. Wong 366d299fe7 libext2fs: initialize i_extra_isize when writing EAs ... If i_extra_isize is zero when we try to write extended attributes, we'll end up writing the EA magic into the i_extra_isize field, which causes a subsequent crash on big endian systems (when we try to write 0xEA02 bytes past the inode!). Therefore when the field is zero, set i_extra_isize to the desired extra_isize size, zero those bytes, and write the EAs after the end of the extended inode. v2: Don't bother if we have 128b inodes, and ensure that the value is 32b-aligned so that the EA magic starts on a 32b boundary.
