Some options loaded a number as a string with getstr and converted it to number with getnum later in the code, without any reason for this approach. (They were probably forgotten in some past cleaning.) This patch changes them to skip the string and use getnum directly in the main option-parsing loop, as do all the other numerical options. And as we now have two variables of the same type for the same value, merge them together. (e.g. former string dsize and number dbytes). Signed-off-by: Jan Tulak <jtulak@redhat.com> --- This patch has to be applied after "mkfs: Save raw user input ...", because otherwise we would temporary lose the access to strings with user-given values and thus wouldn't be able to report them in case of an issue. (In reply to Eric's comment.) UPDATE: * fix dbytes, rtbytes, rtextbytes and logbytes - these variables should be uint64, as the local old ones they are replacing, but were unintentionally created as int --- mkfs/xfs_mkfs.c | 90 ++++++++++++++++++++++++++------------------------------- 1 file changed, 41 insertions(+), 49 deletions(-)
