Date: Sat, 26 Sep 2009 17:19:07 +0800 From: "wilbur.chan" <wilbur512@...il.com> To: linux-kernel@...r.kernel.org Subject: Why get_fs_names return NULL? I am going to start a kernel using ramdisk, but kernel panic when mounting the ramdisk fs. After traped the code , I found that , when kernel invoked get_fs_names, it got a NULL list of existing file system names. That is to say, prepare_namespace--->mount_root-->mount_block_root-->get_fs_names-->get_filesystem_list , return a list of nothing... I thought that , maybe module_init(init_ext2_fs) failed , but I don't know why? and how to solve it ? here is my ramdisk script: mkdir initrd dd if=/dev/zero of=initrd.img bs=1k count=4096 mke2fs -F -v -m0 initrd.img mount -o loop initrd.img initrd cp -av rootfs/* initrd sync umount initrd sync gzip -f -9 initrd.img sync ./mkimage -T ramdisk -C gzip -n ' Ramdisk Image' -d initrd.img.gz your.ramdisk.u-boot -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
