Jean-Sébastien Pédron	8363672729	linuxkpi: Add synchronize_shrinkers() ... It takes the lock and release it immediately to make sure no shrinkers are running in parallel. Reviewed by: manu Approved by: manu Differential Revision: https://reviews.freebsd.org/D38565	2023-02-14 23:01:06 +01:00
Jean-Sébastien Pédron	3aa335d00a	linuxkpi: Add gfp_mask field to struct shrink_control ... bz@ asked if the KBI breakage is a concern here. My answer was that this is the first time in the DRM drivers in Linux 5.13 (the version I'm working on) that this structure is initialized (as a variable local to the function in this case), so it shouldn't be a problem for the DRM drivers. However, I can't speak for other drivers maintained outside of the src tree.

Emmanuel Vadot	2c95fb753f	linuxkpi: Add shrinker support ... A driver can register a shrinker that will be called when the kernel wants to free some memory. Add support for that in linuxkpi and call the registered shrinkers when the lowmem event is triggered.
