Subject: [PATCH] i386/bits/syscalls.h: allow immediate values as 6th syscall
|
|
arg
|
|
|
|
Allow use of immedate values as the 6th syscall argument. Otherwise we must
|
|
store the arg on memory. This gives gcc more options to optimize better.
|
|
|
|
This also works around an issue with posix_fallocate.
