[Qemu-devel] [PATCH v7 0/3] 9p: Fix file ID collisions |

This is v7 of a proposed patch set for fixing file ID collisions with 9pfs.
v6->v7:
* Rebased to https://github.com/gkurz/qemu/commits/9p-next
(SHA1 7fc4c49e91).
* Be pedantic and abort with error on wrong value for new command line
argument 'multidevs'.
* Adjusted patches to qemu code style guidelines.
* Fixed potential crash in qp_table_destroy() on error path.
* Use dedicated hash table init functions (qpd_table_init(),
qpf_table_init(), qpp_table_init()):
https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg00144.html
* Use warn_report_once() instead of error_report_once() for issues
interpreted merely as being warnings, not errors.
* Simplified hash table destruction (due to simplified error path
introduced by SHA1 7fc4c49e91).
* Dropped capturing root_ino for now:
https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg00146.html
* Don't update proxy docs, since new command line argument 'multidevs' is
limited to the local backend for now.
* Mention in docs that readdir() is currently not blocked by
'multidevs=forbid'.
* Rename qid_path_prefixmap() -> qid_path_suffixmap() in patch 3
(due to the semantic change of that function by that patch).

9p: Added virtfs option 'multidevs=remap|forbid|warn'
9p: stat_to_qid: implement slow path
9p: Use variable length suffixes for inode remapping
