Hallo Peter,
there was an e-mail from Eric which you might consider in a 2nd version
of your patch series.
Please check also your patches using scripts/checkpatch.pl. Some of them
currently produce warnings:
total: 0 errors, 1 warnings, 139 lines
checked0001-ui-vnc-introduce-VNC_DIRTY_PIXELS_PER_BIT-macro.patch
total: 0 errors, 6 warnings, 212 lines
checked0003-ui-vnc-optimize-dirty-bitmap-tracking.patch
total: 0 errors, 1 warnings, 17 lines
checked0005-ui-vnc-optimize-setting-in-vnc_dpy_update.patch
I think it would also be reasonable to fix the coding style for this
code location in a separate patch
before modifying the else statement, but maybe this is optional:
else
- w_lim = w - (w_lim % 16);
+ w_lim = w - (w_lim % VNC_DIRTY_PIXELS_PER_BIT);
Viele Grüße
