Hey there,
maybe instead of this rather specific, niche readfile syscall, would it not be
beneficial
to allow issuing any group or bundle of several arbitrary system calls so this
could also
be used to speed up other, more demanding high performance applications that
need
a bit more than just readfile()?
An iImplementation could use some SYSCALLV syscall taking some io_uring like
structure with a list of flags, syscalls and arguments, so that this case could
be submitted
as something like (illustration purposes only):
{
{ABORT_ON_ERROR, OPEN, …},
{RET_TO_ARG1, READ, …},
{0, CLOSE, …},
}
I hope that sounds useful,
René Rebe
