Subject: [PATCH] file: zero: Print the debug message on the fallback path once
|
|
|
|
Use the new ONCE() macro to print the debug message when we fall back
|
|
to emulating zero only once. (Actually the core server code contains
|
|
a similar message so we probably don't need this at all.)
|
|
|
|
(cherry picked from commit fbb5d8211bf4c30144d01be80720e1a63ecd6e81)
