System: NetBSD guava.gson.org 7.2 NetBSD 7.2 (GENERIC.201808291900Z) amd64
Architecture: x86_64
Machine: amd64
>Description:

Running the ATF tests on real multi-core hardware, the
udf_renamerace_dirs test case of the fs/vfs/t_renamerace test fails
every time, with "mkdir: No space left on device".  For example:

  http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2019/2019.01.10.23.10.23/test.html#fs_vfs_t_renamerace_udf_renamerace_dirs

Running under qemu on the TNF testbed, it passes every time.

See also 49046, "udf_renamerace test randomly fails".

Subject: PR/53865 CVS commit: src/tests/fs/vfs
Date: Sun, 13 Jan 2019 14:35:00 +0000

 Module Name:	src
 Committed By:	gson
 Date:		Sun Jan 13 14:35:00 UTC 2019

 Modified Files:
 	src/tests/fs/vfs: t_renamerace.c

 Log Message:
 Mark the fs/vfs/t_renamerace:udf_renamerace_dirs test case as an
 expected failure referencing PR kern/53865, and force failure to avoid
 reports of unexpected success as it does not realiably fail under
 qemu.  This makes the treatment of udf_renamerace_dirs the same as
 that of udf_renamerace, only with a different PR.  Also, make
 whitespace consistent between the two.
