Subject: tests: check non-verbose decoding of LOOP_* ioctls
X-Git-Tag: v4.16~95
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=23287f11fe9e41ed47de2bdaa404ef6f20479d02;p=strace

tests: check non-verbose decoding of LOOP_* ioctls

* tests/ioctl_loop-nv.c: New file.
* tests/ioctl_loop-nv.test: New test.
* tests/ioctl_loop.c [!ABBREV] (ABBREV): Define to 0.
(print_loop_info, print_loop_info64): Handle [ABBREV != 0] case.
* tests/.gitignore: Add ioctl_loop-nv.
* tests/Makefile.am (check_PROGRAMS): Likewise.
