/usr/include/linux/limits.h:#define XATTR_NAME_MAX   255 /* # chars in an extended attribute name */

/usr/src/linux-headers-4.15.0-54/include/uapi/linux/limits.h:#define NAME_MAX         255 /* # chars in a file name */

/usr/src/linux-headers-4.15.0-54/include/uapi/linux/limits.h:#define XATTR_NAME_MAX   255 /* # chars in an extended attribute name */

/usr/src/linux-headers-4.15.0-151/include/uapi/linux/limits.h:#define NAME_MAX         255 /* # chars in a file name */
