Hi, <br><br>I want to use compcache 0.3 release as ramfs, which could be used for processes for shred memory communication.<br>Currently, I compcache acts as virtual block driver and act as swap Filesystem<br><br>1) swapoff compcache partition<br>
2) mkfs.vfat -F 32 -S 4096 /dev/ramzswap0<br>3) mount /dev/ramzswap0 /mnt </blockquote><div><br>ramzswap is not a generic block device, so as I understand you cannot mount normal filesystems on it (It only supports I/O of size PAGE_SIZE).<br>
<br>Would something like the following suffice?<br><br>1) swapon /dev/ramzswap<br>2) mount -t <tt>tmpfs -o size=1G,nr_inodes=10k,mode=0700 tmpfs /space</tt><br><br><a href="http://en.wikipedia.org/wiki/TMPFS">http://en.wikipedia.org/wiki/TMPFS</a><br>
<br>The linux kernel should swap out tmpfs pages that have not been frequently used, so this should be fairly close to what you want. tmpfs is probably a better fit for this than vfat anyway.<br> </div></div><br clear="all">
