[Gluster-devel] optimizing gluster fuse

[riya khanna]

Hi,

I've modified FUSE framework to take a part of user-space daemon code and
moves it into the kernel fuse driver to minimize user-kernel-user switches
during file system  operations. An example would be caching
getattr/getxattr/lookup/security checks etc. This design, therefore,
create fast (served directly from the kernel) and a slow (regular fuse)
execution paths. The fast and slow paths can also communicate with each
other using shared memory.

I was wondering if it is possible to accelerate glusterfs using this
design. What pieces could (should) be easily moved to kernel space? Any
pointers would be highly appreciated. Thanks!
