Subject: [PATCH 1/3] syscalls: clean up syscall stub naming convention
Tidy the naming convention for compat syscall subs. Hints which describe
the purpose of the stub go in front and receive a double underscore to
denote that they are generated on-the-fly by the SYSCALL_DEFINEx() macro.
For the generic case, this means (0xffffffff prefix removed):
810f08d0 t kernel_waitid # common C function (see kernel/exit.c)
<inline> __in_sys_waitid # inlined helper doing the actual work
# (takes parameters as declared)
810f1aa0 T __do_sys_waitid # C function calling inlined helper
# (takes parameters of type long; casts
# them to the declared type)
810f1aa0 T sys_waitid # alias to __do_sys_waitid() (taking
# parameters as declared), to be included
# in syscall table
For x86, the naming is as follows:
810efc70 t kernel_waitid # common C function (see kernel/exit.c)
<inline> __in_sys_waitid # inlined helper doing the actual work
# (takes parameters as declared)
810efd60 t __do_sys_waitid # C function calling inlined helper
# (takes parameters of type long; casts
# them to the declared type)
810f1140 T __ia32_sys_waitid # IA32_EMULATION 32-bit-ptregs -> C stub,
# calls __do_sys_waitid(); to be included
# in syscall table
810f1110 T sys_waitid # x86 64-bit-ptregs -> C stub, calls
# __do_sys_waitid(); to be included in
# syscall table
For x86, sys_waitid() may be re-named to __x64_sys_waitid in a follow-up
patch.
