Then you could use the donor inode method to move things around. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJP+yfPAAoJEJrBOlT6nu75Y8AH/09qDUt0jdhPjNyXMUUFRVaV U7Ih5j6r0srRHH9VmS7ppq6ingqpbrFEExbalg8ynTRX1nYDGL0nLiBU79rfK+KK XOTK0ZYm+CUMElLdO5bYnaHti9vsSHL5xRyGmI5OR0CY7LwfnyJeDw6wS7+WsgyQ o6ziTPcBEfaJzn9BBS+EP/1WI06lQ/cJbWUqUAJhefu2my3IXJUrjUYjnH46HKGM 2ptPbIJM2fT4QubBNnuPpdTNI5yc56+auzoB3hrK2Nf/Yh17w5R0MomHk/VitzPt AD7zKLgpk6R9G/IbnajsMVzbLsjBbn8Tcyrhher2uyw3xE0XtJgj2fmPq32ZrL0= =hMeu -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
