| |
Hi Linus,
Could you consider this pull request for 5.11-rc1?
This cycle we'd like to get rid of magical page->mapping type marks for temporary pages which had some concern before, now such usage is replaced with specific page->private. Also switch to inplace I/O instead of allocating extra cached pages to avoid direct reclaim under low memory scenario. There are some bmap bugfix and minor cleanups as well.
All commits have been tested and have been in linux-next for a while. This merges cleanly with master.
[ Additionally, there is another lz4 inplace decompression fix [1] due to some different overlapped memcpy() implementation which was reviewed and added to akpm tree, hopefully upstream for this 5.11 cycle too. ]
Thanks, Gao Xiang
