[PATCH v3 0/7] 9pfs: fix 'Twalk' protocol violation |

Currently the implementation of 'Twalk' does not behave exactly as specified
by the 9p2000 protocol specification. Actual fix is patch 5; see the
description of that patch for details of what this overall fix and series is
about.
Patch 4 is a preparatory (pure) refactoring change to make patch 5 better
readable.
All the other patches are just additional test cases for guarding 'Twalk'
behaviour.
v2 -> v3:
* Use 'any_err |= err = ...' at all occurrences to make v9fs_walk() function
less error prone, which also reduces lines of code. [patch 5]
Christian Schoenebeck (7):
tests/9pfs: walk to non-existent dir
tests/9pfs: Twalk with nwname=0
tests/9pfs: compare QIDs in fs_walk_none() test
9pfs: refactor 'name_idx' -> 'nwalked' in v9fs_walk()
9pfs: fix 'Twalk' to only send error if no component walked
tests/9pfs: guard recent 'Twalk' behaviour fix
tests/9pfs: check fid being unaffected in fs_walk_2nd_nonexistent
