Subject[PATCH] fs/reiserfs: replace ternary operator with min() and min_t()
Date
From: Jiangshan Yi <yijiangshan@kylinos.cn>

Fix the following coccicheck warning:

fs/reiserfs/prints.c:459: WARNING opportunity for min().
fs/reiserfs/resize.c:100: WARNING opportunity for min().
fs/reiserfs/super.c:2508: WARNING opportunity for min().
fs/reiserfs/super.c:2557: WARNING opportunity for min().

min() and min_t() macro is defined in include/linux/minmax.h.
It avoids multiple evaluations of the arguments when non-constant and
performs strict type-checking.
