[PATCH 09/39] resize2fs: don't exit if shrinking sparse_super2 fs to one bg

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If we're shrinking a sparse_super2 filesystem to a single block group,
the superblock will be in block 0.  This is perfectly valid (for block
group 0 with a blocksize > 1024) so don't exit.
