Copy the description of v3 cover letter from Willy: === For some reason several people have been sending bad patches to fix compiler warnings in vmcore recently. Here's how it should be done. Compile-tested only on x86. As noted in the first patch, s390 should take this conversion a bit further, but I'm not inclined to do that work myself. This series resends Willy's v3 patches which includes patch 1~3, and append one patch to clean up the open code pointed out by Al. Al's concerns to v3 patches and my reply after investigation: https://lore.kernel.org/all/YhiTN0MORoQmFFkO@MiWiFi-R3L-srv/T/#u Willy's v3 patchset: [PATCH v3 0/3] Convert vmcore to use an iov_iter https://lore.kernel.org/all/20211213143927.3069508-1-willy@xxxxxxxxxxxxx/T/#u Changelog: === v4: - Append one patch to replace the open code with iov_iter_count(). This is suggested by Al. - Fix a indentation error by replacing space with tab in arch/sh/kernel/crash_dump.c of patch 1 reported by checkpatch. The rest of patch 1~3 are untouched. - Add Christopy's Reviewed-by and my Acked-by for patch 1~3. v3: - Send the correct patches this time v2: - Removed unnecessary kernel-doc - Included uio.h to fix compilation problems - Made read_from_oldmem_iter static to avoid compile warnings during the conversion - Use iov_iter_truncate() (Christoph) Baoquan He (1): fs/proc/vmcore: Use iov_iter_count() Matthew Wilcox (Oracle) (3): vmcore: Convert copy_oldmem_page() to take an iov_iter vmcore: Convert __read_vmcore to use an iov_iter vmcore: Convert read_from_oldmem() to take an iov_iter arch/arm/kernel/crash_dump.c | 27 +------ arch/arm64/kernel/crash_dump.c | 29 +------ arch/ia64/kernel/crash_dump.c | 32 +------- arch/mips/kernel/crash_dump.c | 27 +------ arch/powerpc/kernel/crash_dump.c | 35 ++------- arch/riscv/kernel/crash_dump.c | 26 +------ arch/s390/kernel/crash_dump.c | 13 ++-- arch/sh/kernel/crash_dump.c | 29 ++----- arch/x86/kernel/crash_dump_32.c | 29 +------ arch/x86/kernel/crash_dump_64.c | 48 ++++-------- fs/proc/vmcore.c | 130 +++++++++++++------------------ include/linux/crash_dump.h | 19 ++--- 12 files changed, 123 insertions(+), 321 deletions(-) -- 2.34.1
