Hi Linus,
Could you consider these fixes for 6.8-rc3?
One commit fixes an infinite loop issue of sub-page compressed data
support found with lengthy stress tests on a 64k-page arm64 VM.
Another one optimizes temporary buffer allocation for low-memory
scenarios, which can reduce 20.21% on average under a heavy multi-app
launch benchmark workload.
The remaining one gets rid of unnecessary GFP_NOFS.
All commits have been in -next for a while and no potential merge
conflict is observed.
Thanks,
Gao Xiang
