[PATCH net v2 0/4] netconsole: configfs store callback fixes

[Breno Leitao]

V2 for issues in netconsole's configfs store callbacks.

There are still some changes I want to make, such as, having the dynamic
lock when reading from configfs (_show() callbacks), wich will solve
other issues, but I will keep it for later.

Changes in v2:
- dev_name_store: strip optional trailing newline before length check
  so 15-char ifnames written via echo aren't rejected (Simon, Sashiko)
- userdatum_value_store: snapshot and restore udm->value on
  update_userdata() failure to keep visible state in sync with the live
  payload (Simon/Sashiko)

Breno Leitao (4):
      netconsole: return count instead of strnlen(buf, count) from store callbacks
      netconsole: avoid clobbering userdatum value on truncated write
      netconsole: propagate device name truncation in dev_name_store()
      netconsole: restore userdatum value on update_userdata() failure
