a directory hierarchy to another point, just like with the kernel
nullfs. This is not really a layering scheme yet, but it should
evolve into one. Currently it can just be used to do 1:1 mapping.
server that it needs to mount the file system backend if it wants
to call mount
* provide some options for getmntopts(), assume that callers will parse
command line (or fstab) args
* reorganize the puffs_cc interface just a bit, preparing for a bigger
revamp later
Add support for having multiple outstanding operations. This is done
by exposing enough interfaces so that it is convenient to have the
main event loop in the implementation itself and by providing a
continuation framework for convinient blocking and rescheduling.
works fine, but will undergo further cleanup & development
This work was initially started and completed for Google SoC 2005
and tweaked to work a bit better in the past few weeks. While
being far from complete, it is functional enough to be able and
stable to host a fairly general-purpose in-memory file system in
userspace. Even so, puffs should be considered experimental and
no binary compatibility for interfaces or crash-freedom or zero
security implications should be relied upon just yet.
The GSoC project was mentored by William Studenmund and the final
review for the code was done by Christos.
