# Test multiple fallocate collapse range calls on same file.
|
|
# For different blocksizes, collapse a single alternate block multiple times
|
|
# until the file is left with 80 blocks and as much number of extents.
|
|
# Also check for file system consistency after completing this operation
|
|
# for each blocksize.
