ext4: wait for log to commit when umounting
There is a potential race when a transaction is committing right when the file system is being umounting. This could reduce in a race because EXT4_SB(sb)->s_group_info could be freed in ext4_put_super before the commit code calls a callback so the mballoc code can release freed blocks in the transaction, resulting in a panic trying to access the freed s_group_info. The fix is to wait for the transaction to finish committing before we shutdown the multiblock allocator. Signed-off-by: Josef Bacik <josef@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
