如何在linux中的客户端CIFS(samba)中禁用缓存

/etc/modprobe.d/cifs.conf
-------------------------
# Disable caching and the CIFS oplog for stable NTFS network shares
options cifs enable_oplocks=0

install cifs /sbin/modprobe --ignore-install cifs $CMDLINE_OPTS && echo 0 > /proc/fs/cifs/LinuxExtensionsEnabled && echo 0 > /proc/fs/cifs/LookupCacheEnabled
remove cifs /sbin/modprobe -r cifs

这是一个确定有效模块选项的便捷功能.

# Shamelessly ripped the Kernel_Modules ArchWiki entry:
# https://wiki.archlinux.org/index.php?title=Kernel_modules&oldid=286087#Bash_function_to_list_module_parameters 

function aa_mod_parameters ()
{
    N=/dev/null;
    C=`tput op` O=$(echo -en "n`tput setaf 2`>>> `tput op`");
    for mod in $(cat /proc/modules|cut -d" " -f1);
    do
        md=/sys/module/$mod/parameters;
        [[ ! -d $md ]] && continue;
        m=$mod;
        d=`modinfo -d $m 2>$N | tr "n" "t"`;
        echo -en "$O$m$C";
        [[ ${#d} -gt 0 ]] && echo -n " - $d";
        echo;
        for mc in $(cd $md; echo *);
        do
            de=`modinfo -p $mod 2>$N | grep ^$mc 2>$N|sed "s/^$mc=//" 2>$N`;
            echo -en "t$mc=`cat $md/$mc 2>$N`";
            [[ ${#de} -gt 1 ]] && echo -en " - $de";
            echo;
        done;
    done
}

此外,CIFS安装遵循缓存选项.根据the mount.cifs manual,设置cache = none应禁用缓存,而默认值为cache = strict.
