Subject: mke2fs, tune2fs: call proceed_question() from check_plausibility()'s caller
X-Git-Tag: v1.42.10~40
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d69f43f56a215b3335d8cf853b6521715e90b769;p=thirdparty%2Fe2fsprogs.git

mke2fs, tune2fs: call proceed_question() from check_plausibility()'s caller

Move the call to proceed_question() from check_plausibility() to its
caller.  This allows more fine grained control by mke2fs about when it
might want to call check_plausibility().
