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
