page buf meta data and FS corruption

[Jim Mostek <mostek@xxxxxxx>]

I was running with page buf meta data turned on and XFSDEBUG and DEBUG.

I did lots of stuff on an XFS file system including building the
kernel: make clean, make dep, ...

Then, I noticed with top that 113MB or the 128MB of memory were in use.
I did an unmount and this went down to 30MBs. I'm guessing that we had
lots in cache.

After the unmount, I did a mount and was going to run some performance
numbers. The first file create resulted in the following ASSERT:

linux/fs/xfs/xfs_inode.c:xfs_ialloc()

        ASSERT(ip->i_d.di_nblocks == 0);

The newly allocated inode file has some blocks?

You mentioned that there is a known problem where we don't fully release
page bufs when unmounting. Could this be related? Should I open a PV for this?

Thanks,

Jim
