Its filename was zram-remove-unreachable-kernel_read_file_from_path-return-check.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Sergey Senozhatsky Subject: zram: remove unreachable kernel_read_file_from_path() return check Date: Tue, 1 Sep 2026 14:13:05 +0900 Sashiko reported that: kernel_read_file_from_path() returns negative error for zero-sized files, so we cannot have "sz == 0" return, remove it and use a generic error message instead.
