Subject: resize: Remove p_size field from partitions structure.
X-Git-Tag: 1.13.23~5
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=9f198956047583e506713a4472117922f8b27b2e;p=libguestfs.git

resize: Remove p_size field from partitions structure.

This field simply contained a duplicate copy of p_part.part_size.

There is no functional change in this commit.
