[bug-patch] [Patch] - Separated patch hunk FAIL or ignored from *.rej to different suffix filename.

[? ??]

By default.  ether patch "FAIL" or "ignored" hunks saved in the same file name.
However, In mostly case, We only care "FAIL" hunks from *.rej.
The patch can not separate two case(FAIL/Ignored)  in different suffix filename.

$ patch --dry-run -p1 -d backports/ --forward -N  < kernel_v4.9.patch
