| Subject: kexec: Fix make headers_check |
| |
| commit 9dc5c05f45ca8101025046cda7f8aca8835204f2 upstream. |
| |
| Remove the unneded declaration for a kexec_load() routine. |
| |
| Fixes errors like these when running 'make headers_check': |
| |
| include/uapi/linux/kexec.h: userspace cannot reference function or variable defined in the kernel |
| |
| Paul said: |
| |
| : The kexec_load declaration isn't very useful for userspace, see the patch |
| : I submitted in http://lkml.kernel.org/r/1389791824.17407.9.camel@x220 . |
| : And After my attempt the export of that declaration has also been |
| : discussed in |
| : http://lkml.kernel.org/r/115373b6ac68ee7a305975896e1c4971e8e51d4c.1408731991.git.geoff@infradead.org |
| : |
| : In that last discussion no one has been able to point to an actual user of |
| : it. So, as far as I can tell, no one actually uses it. Which makes |
| : sense, because including this header by itself doesn't give one access to |
| : a useful definition of kexec_load. So why bother with the declaration? |
