Subject: tests: fix xattr.test for the case when listxattr returns a long list
X-Git-Tag: v4.16~292
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d9d92cf220d99ba4354f564f2edb46445f4da91b;p=strace

tests: fix xattr.test for the case when listxattr returns a long list

* tests/xattr.c (DEFAULT_STRLEN): New macro.
(main): Use it to limit the length passed to print_quoted_memory.
Print ellipsis when the list returned by listxattr is too long.
