New Revision: 210138
URL: http://svn.freebsd.org/changeset/base/210138
Log:
Retire td_syscalls now that it is no longer needed.
Modified:
head/sys/kern/kern_thread.c
head/sys/kern/subr_trap.c
head/sys/sys/proc.h
Did you want to leave the field as a placehgolder or add a note
somewhere that people should do a full recompile because the layout
changed?
Make depend should do the magic, right ?
right, I am more worried about (out of tree) modules. struct thread
is basically everywhere with curthread and thread * passed around and
modules will not refuse to load as freebsd_version hasn't changed.
I was surprised to see that mips/arm did not touched td_syscalls, and
I wonder how much other bugs are lurking in their implementation.
Modified: head/sys/sys/proc.h
