* gfapi: optimistic resolution with ESTALE detectionAnand Avati2013-05-251-2/+2
| | | | | | | | | | | | | | | | | | | Enhance the path resolver to be optimistic. Instead of performing a wasteful ->lookup() fop for every component in every API call, build in speculation logic to consider the previous resolution result temporarily, and if it results in ESTALE either later in the path resolution or in the FOP, then retry resolution with ->lookup() at every level and retry the FOP. This is the same optimistic resolution/retry logic Linux kernel resolver is proposing to use.
