io_cancel on score
cancel an outstanding asynchronous I/O operation
sys_io_cancel(aio_context_t ctx_id, struct iocb *iocb, struct io_event *result)| number | 3 (0x3) |
|---|---|
| abi | common |
| kconfig | CONFIG_AIO |
| family | aio see the whole family on score |
| entry point | sys_io_cancel |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | io_cancel(2) |

Registers
| register | value |
|---|---|
r27 | 3, the syscall number |
r4 | aio_context_t ctx_id |
r5 | struct iocb *iocb |
r6 | struct io_event *result |
r4 | the return value |
Then run syscall to enter the kernel.
r7 is the error flag and r4 then holds the positive error number.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
