Since we're so close to release, it seems better to just simply revert it, and we can figure out what's going on without leaving it broken for a release. - Revert crypto acomp migration (Guilherme G. Piccoli)" * tag 'pstore-v6.0-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: Revert "pstore: migrate to crypto acomp interface" 2022-09-30T15:16:06Z Guilherme G. Piccoli gpiccoli@igalia.com 2022-09-29T21:55:15Z urn:sha1:40158dbf7eb2b13d8851fe0b875b4c3170ea15db This reverts commit e4f0a7ec586b7644107839f5394fb685cf1aadcc. When using this new interface, both efi_pstore and ramoops backends are unable to properly decompress dmesg if using zstd, lz4 and lzo algorithms (and maybe more). It does succeed with deflate though. The message observed in the kernel log is: [2.328828] pstore: crypto_acomp_decompress failed, ret = -22! The pstore infrastructure is able to collect the dmesg with both backends tested, but since decompression fails it's unreadable. With this revert everything is back to normal.

Fix by providing a variant of __kernel_write() that takes an iov_iter from caller (__kernel_write() becomes a trivial wrapper) and adding dump_emit_page() that parallels dump_emit(), except that instead of __kernel_write() it uses __kernel_write_iter() with ITER_BVEC source.
