Subject: dtrace: remove functionality of dtrace_os_exit() as deprecated
X-Git-Tag: v4.1.12-92~313^2~51
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e52b05225632cda0900823edb726af4f6cbb4f09;p=users%2Fjedix%2Flinux-maple.git

dtrace: remove functionality of dtrace_os_exit() as deprecated

This function is in its current form no longer called from anywhere, but since
it is exported someone could (maliciously) still call it and cause a mess.  We
therefore issue a warning and do not do anything else.  This will be removed in
a future version.
