The kmaps in compression code are still needed and cause crashes on 32bit machines (ARM, x86). Reproducible eg. by running fstest btrfs/004 with enabled LZO or ZSTD compression. and the followon commits from Linus Torvals and Qu Wenruo -- You are receiving this mail because: You are the assignee for the bug.
