Since version 2.1 the return value of a system call might be negative
|
||||
even if the call succeeded. E.g., the `lseek' system call might return
|
||||
a large offset. Therefore we must not anymore test for < 0, but test
|
||||
for a real error by making sure the value in %d0 is a real error
|
||||
number. Linus said he will make sure the no syscall returns a value
|
||||
in -1 .. -4095 as a valid result so we can savely test with -4095. */
