Hello,

Is there any documentation on the locking requirements for the various uvm_* calls, beyond the comments in uvm_page.h?  I'm looking at a panic caused by a failed assertion coming eventually from the error case in lfs_gop_write.  I can arrange not to trigger that particular assertion, but I'd be more confident if I had documentation to refer to.

Thanks,
