Wolfram Sang f3a6e79c58 mtd: tests: stresstest: bail out if device has not enough eraseblocks ... commit 2f4478ccff upstream. stresstest needs at least two eraseblocks. Bail out gracefully if that condition is not met. Fixes the following 'division by zero' OOPS: [ 619.100000] mtd_stresstest: MTD device size 131072, eraseblock size 131072, page size 2048, count of eraseblocks 1, pages per eraseblock 64, OOB size 64 [ 619.120000] mtd_stresstest: scanning for bad eraseblocks [ 619.120000] mtd_stresstest: scanned 1 eraseblocks, 0 are bad [ 619.130000] mtd_stresstest: doing operations [ 619.130000] mtd_stresstest: 0 operations done [ 619.140000] Division by zero in kernel. ... caused by /* Read or write up 2 eraseblocks at a time - hence 'ebcnt - 1' */ eb %= (ebcnt - 1); Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>		2012-01-25 17:24:32 -08:00
