ext4: discard preallocation during truncate
We need to make sure when we drop and reacquire the inode's
i_data_sem we discard the inode preallocation. Otherwise we
could have blocks marked as free in bitmap but still belonging
to prealloc space.
Just wanted to let you know that I have applied this patch and one
unclean shutdown later it seems to have not given me any trouble.
I will continue testing it - hopefully I won't have to reformat this
time ( every time I tested previously I ended up having weird issues
that I decided to get rid of by reformatting /).
I've been running my testcase, and I just hit the usual corruption with
this patch in place after 8 iterations, I'm afraid.
