Details

Summary

The reason why list_for_each_entry() is being redefined here is because unlike the Linux version, FreeBSD's list_for_each_entry() does not use locks.

This is needed by the drm-kmod 5.7 update.

nc retitled this revision from Add list_for_each_entry_lockless() macro to linuxkpi: Add list_for_each_entry_lockless() macro.Jun 9 2021, 6:23 PM

If it's the same as list_for_each_entry you should explain why in the commit message.

I believe linuxkpi's list_for_each_entry is lockless (but am not sure), so I updated the message.

Please use function macro.

#define list_for_each_entry_lockless(...) list_for_each_entry(__VA_ARGS__)

--HPS

Using function macro as per @hselasky's suggestion.
