The patch titled fix param_sysfs_builtin name length check has been removed from the -mm tree. Its filename was fix-param_sysfs_builtin-name-length-check.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: fix param_sysfs_builtin name length check From: Jan Kiszka <jan.kiszka@xxxxxx> Commit faf8c714f4508207a9c81cc94dafc76ed6680b44 caused a regression: parameter names longer than MAX_KBUILD_MODNAME will now be rejected, although we just need to keep the module name part that short. This patch restores the old behaviour while still avoiding that memchr is called with its length parameter larger than the total string length.
