Am in the midst of bringing up the kernel on a new MIPS variant, and I'm tryingthe mount a statically linked ramdisk as the root filesystem.
Note, this is NOT using initrd support, I really want to use a ramdisk as my final filesystem, not as an intermediate step in booting the system.
In blkdev_get(), called from mount_root(), there's some code that grabs an empty inode, sets up i_rdev, and calls open() for the root device with the caveat that open() must not examine anything except i_rdev.
in rd_open, though, there's this code snippet:
/* * Immunize device against invalidate_buffers() and prune_icache(). */ if (rd_inode[DEVICE_NR(inode->i_rdev)] == NULL) { if (!inode->i_bdev) return -ENXIO;
I'm hitting the -ENXIO return, which is based on an uninitialized field of the inode structure.
Being relatively new to the code base, I'm not sure what this code is trying to do, nor how to fix it. Any suggestions?
The code involved is from the MIPS CVS repository at oss.sgi.com, which was synced in the past couple days from 2.4.0test11
