[PATCH 1/2] uprobe: Change uretprobe syscall scope and number

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After discussing with Arnd [1] it's preferable to change uretprobe
syscall number to 467 to omit the merge conflict with xattrat syscalls.

Also changing the ABI to 'common' which will ease up the global
scripts/syscall.tbl management. One consequence is we generate uretprobe
syscall numbers for ABIs that do not support uretprobe syscall, but the
syscall still returns -ENOSYS when called in that ABI.
