[Please CC all replies] Hi, I just found a small bug in the way ramdisks work - it was introduced sometime between 2.4.10 and 2.4.15. I haven't yet been able to try 2.4.17, but I didn't see anything too evident in the patch/changelog. Basically, if you use a filesystem with a blocksize that is not BLOCK_SIZE then when the filesystem super block is loaded set_blocksize will be called which will call kill_bdev which calls truncate_inode_pages on the rd mapping - that ends up destroying the ramdisk. I found this while using cramfs as an initrd, a hackish work around in my case is to change the default block size of the ramdisk - I'm not sure what the real fix should be. Hope this helps, Jason - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | |||||||||
