[PATCH 06/16] block: unhash the inode earlier in delete_partition

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

 



Move the call to remove_inode_hash to the beginning of delete_partition,
as we want to prevent opening a block_device that is about to be removed
ASAP.
