Add -r switch to src/bulkstat_unlink_test.c needed for QA test 183
(whitespace cleanups) This patch adds a -r switch (using getopt as suggested by dchinner) to src/bulkstat_unlink_test.c, that will implement the additional checks described by vlad in PV 972128. Basically we: * Save the inode count in scount. * Create nfiles new files (passed as argument). * Open those nfiles. * Unlink the files. * Check that the inode count is greater than scount. * close the files. * Check that the inode count is the same as scount. This patch also introduces more info on failure (Line number and file) before the exit()s, as well as comments describing what we are doing. This patch is to be used by QA test 183 SGI-Git-Id: 4ab8fa354f79070b4ba87cb09c4326d62da824fd SGI-Git-author: Niv Sardi-Altivanik <xaiki@chook.melbourne.sgi.com> SGI-Git-date: Wed, 24 Oct 2007 13:24:27 +1000 Merge of master-melb:xfs-cmds:29964a by kenmcd.
