Commit Message

Chandan Rajendra Nov. 23, 2018, 5:59 a.m. UTC
This commit changes the script to operate on FS blocks by obtaining the
block size from the underlying filesystem and using it to perform I/O in
units of block sizes.

This commit also uses $SCRATCH_MNT rather than $TEST_DIR for holding the
test files since the FS on $TEST_DIR might be created with a different
block size than the one specified in $MKFS_OPTIONS.
