CVS commit: src/sys/coda



Module Name:    src
Committed By:   gdt
Date:           Fri Apr  6 22:28:12 UTC 2007

Modified Files:
        src/sys/coda: coda_vnops.c

Log Message:
Disable mmap for coda.  When copying a file from coda to normal ffs, I
got a panic in uvm_fault from ffs_write.  I believe this is because cp
used mmap, the container file page was not in core, and uvm_fault
objected to the container file vnode and the coda vnode not matching.
I have long been plagued by crashes on cp from coda, and this was the
first time I got and understood a backtrace.

Clean up old comments that are no longer accurate.

Document refcounting better.

Note some questionable behaviors with XXX.

Clean up PNBUF_PUT and SAVESTART.  Only do this where vnodeops(9) says
we should, and do it on error also.

In symlink, vput parent and free namebuf even in error cases.
