Subject: SUNRPC: Refactor rpc_show_tasks
X-Git-Tag: v2.6.27-rc1~1052^2~1^2~52
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=38e886e0c18975543938519254fc9bf0829c75a3;p=linux-2.6

SUNRPC: Refactor rpc_show_tasks

Clean up: move the logic that displays each task to its own function.
This removes indentation and makes future changes easier.
