This series backports 27 patches to update minmax.h in the 5.10.y branch, aligning it with v6.17-rc7.
The ultimate goal is to synchronize all long-term branches so that they include the full set of minmax.h changes.
- 6.12.y has already been backported; the changes are included in v6.12.49.
- 6.6.y has already been backported; the changes are included in v6.6.109.
- 6.1.y has already been backported; the changes are currently in the 6.1-stable tree.
- 5.15.y has already been backported; the changes are currently in the 5.15-stable tree.
With this series applied, on an arm64 server, building 'allmodconfig', I get the following build error.
Oddly I don't see it on my x86 server, perhaps due to different compiler versions?
Any ideas?
thanks,
