Fabio M. De Francesco ebd23482ef btrfs: zstd: replace kmap() with kmap_local_page() ... The use of kmap() is being deprecated in favor of kmap_local_page(). With kmap_local_page(), the mapping is per thread, CPU local and not globally visible. Therefore, use kmap_local_page() / kunmap_local() in zstd.c because in this file the mappings are per thread and are not visible in other contexts. In the meanwhile use plain page_address() on output pages allocated with the GFP_NOFS flag instead of calling kmap*() on them (since they are always allocated from ZONE_NORMAL). Tested with xfstests on QEMU + KVM 32 bits VM with 4GB of RAM, booting a kernel with HIGHMEM64G enabled. Suggested-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Fabio M.
