Subject: [PATCH] copy: Avoid potential divide by zero when source size is zero
|
|
|
|
Actually this does not happen because of the way the progress bar is
|
|
called from other code, but it's possible that a future change might
|
|
introduce a bug, so avoid any problems.
|
|
|
|
(cherry picked from commit 266c6e7083b1e0e8373ce166cf0be388604ca805)
