[PATCH] fstests: generic/042: increase filesystem image size

[PATCH] fstests: generic/042: increase filesystem image size

[Anand Jain]

During testing for shutdown, I found that generic/042 sets a size of
25M, which is too small for btrfs. Setting it to 128M.

wrote 26214400/26214400 bytes at offset 0
25 MiB, 6400 ops; 0.0468 sec (533.618 MiB/sec and 136606.1900 ops/sec)
ERROR: '/mnt/scratch/042.img' is too small to make a usable filesystem
ERROR: minimum size for each btrfs device is 114294784
