net-fs/ksmbd-tools-3.4.4 /etc/init.d/ksmbd contains this: start_pre() { /sbin/modprobe ksmbd || return 1 } It's wrong. If the module is already in the kernel image, modprobe fails. It probably fails when the module is loaded manually too. Proposed change: if [ ! -d /sys/module/ksmbd ] then /sbin/modprobe ksmbd fi Thanks.
modprobe should silently exit if module loaded/is in kernel. --first-time Normally, modprobe will succeed (and do nothing) if told to insert a module which is already present or to remove a module which isn't present. This is ideal for simple scripts; however, more complicated scripts often want to know whether modprobe really did something: this option makes modprobe fail in the case that it actually didn't do anything # zcat /proc/config.gz | grep EXT4 CONFIG_EXT4_FS=y ^ as you see ext4 is builtin. # modprobe ext4 # echo $? 0 what's your implementation of modprobe? mine is: qfile /sbin/modprobe sys-apps/kmod: /sbin/modprobe so even if ti try modprobing it, it will return 0. || exit 1 is to catch situations when it actually failed. maybe it's actually failing in your case? like same kernel build with it builtin and still a leftover module present from previous build of same version?
please also provide output of modinfo ksmbd as an example: modinfo ext4 name: ext4 filename: (builtin) softdep: pre: crc32c license: GPL file: fs/ext4/ext4 description: Fourth Extended Filesystem author: Remy Card, Stephen Tweedie, Andrew Morton, Andreas Dilger, Theodore Ts'o and others alias: fs-ext4 alias: ext3 alias: fs-ext3 alias: ext2 alias: fs-ext2 also it does NOT have directory in /sys/module/ext4, so that check is not correct, at least not for ext4.

Can you attach kernel config? Is module support enabled at all? Maybe you can strace modprobe invocation? I can’t reproduce on kernel where modules are enabled but ksmbd is builtin.

thanks. after thinking about it I opted to ignore return codes by running 'modprobe -q ksmbd || return 0' there's little value of checking for error here tbh.
OK. Thanks.
