[PATCH 07/10] block: don't call invalidate_partition from blk_drop_partitions

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

 



Given that the device must not be busy, most of the calls from
invalidate_partition that are related to file system metadata are
guranteed to not happen.  Just open code the calls to sync_blockdev
and invalidate_bdev instead.
