From d61792d0f5fa1e313ec216a5dcb833381cbec92b Mon Sep 17 00:00:00 2001 From: Steve Guminski Date: Wed, 25 Jan 2017 16:41:10 -0500 Subject: [PATCH] LU-6210 utils: Use C99 struct initializers in lfs_setstripe() This patch makes no functional changes. Struct initializers that use C89 or GCC-only syntax are updated to C99 syntax. Whitespace is corrected to match the coding style guidelines. Variables of type struct option have been renamed to long_opts for consistency. C89 positional initializers require values to be placed in the correct order. This will cause errors if the fields of the struct definition are reordered or fields are added or removed. C99 named initializers avoid this problem, and also automatically clear any values that are not explicitly set. This patch updates lfs_setstripe() to use the C99 syntax.
