gfapi: apply an upper bound on nested symlink resolution

2013-09-10T08:16:09+00:00

In case of nested symlink resolution, implement an upper
bound on the number of such nested levels the resolver will
descend. This limit is arbitrary, and set to 2048 nested
levels.

2013-06-08T21:52:52+00:00

2013-06-08T21:51:38+00:00

filesystems (it uses st_dev+st_ino as key to store metadata of
a file).

gfapi: optimistic resolution with ESTALE detection

2013-06-08T21:50:20+00:00

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.
