      "message": "iowatcher: Fix up directory trace processing\n\nSimilar to the fix for spaces in file names in commit 5d845e3, this\npatch fixes processing of directories with spaces in their names by\nusing posix_spawnp() to run the blkparse command instead of system(). In\ndoing so, combine_blktrace_devs() and match_trace() have been reworked\nto use a list structure instead of doing a lot of strdup()ing and string\nappending.\n\nAlso make sure that trailing slashes are removed from the directory name\nbefore attempting to use it as the base of the .dump filename.\n\nUpdate the -t entry in the manpage to mention directory behaviour, too.\n\nSigned-off-by: Andrew Price \u003canprice@redhat.com\u003e\n"

As a result,\nin setup_file() function only part of the file name gets to -\u003efname[].\nThen stat() fails and we exit the function.
