This series fixes sys_getcwd() and symlinks under /proc in case of
unreachable (e.g. lazy unmounted) paths.
The behavior of d_name() is untouched, new helper functions are
introduced instead.
Changes from the previous posting:
- add helpers to get root and pwd from fs_struct (Nick Piggin's comment)
- found and fixed a bug in CacheFiles in this area
- changed ia64/perfmon filesystem to use ->d_dname
- split up into more managable pataches
Thanks,
Miklos
