[PATCH 1/2] xfs: fix incorrect argument count check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



t_mmap_dio.c actually requires 4 arguments, not 3 as the current check
enforces:

usage: t_mmap_dio <src file> <dest file> <size> <msg>
open src(No such file or directory) len 0 (null)
