Updating the block device size from irq context can lead to torn writes of the 64-bit value, and prevents us from using normal process context locking primitives to serialize access to the 64-bit nr_sectors value. Defer the set_capacity to the already existing workqueue handler, where it can be merged with the update of the block device size by using set_capacity_and_notify. As an extra bonus this also adds proper uevent notifications for the resize. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk> |
