The quilt patch titled Subject: fs/proc/kcore.c: clear ret value in read_kcore_iter after successful iov_iter_zero has been removed from the -mm tree. Its filename was fs-proc-kcorec-clear-ret-value-in-read_kcore_iter-after-successful-iov_iter_zero.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------ From: Jiri Olsa jolsa@kernel.org Subject: fs/proc/kcore.c: clear ret value in read_kcore_iter after successful iov_iter_zero Date: Fri, 22 Nov 2024 00:11:18 +0100
If iov_iter_zero succeeds after failed copy_from_kernel_nofault, we need to reset the ret value to zero otherwise it will be returned as final return value of read_kcore_iter.
This fixes objdump -d dump over /proc/kcore for me.
