| * s390/dasd: remove ioctl_by_bdev callsStefan Haberland2020-05-211-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IBM partition parser requires device type specific information only available to the DASD driver to correctly register partitions. The current approach of using ioctl_by_bdev with a fake user space pointer is discouraged. Fix this by replacing IOCTL calls with direct in-kernel function calls.

This causes overhead & complexity in the IRQ path, along with ambiguity in the statistics. On the other hand the device should be in IRQ avoidance mode during a poll cycle, so there won't be a lot of DSCI ping-pong that this micro-optimization could prevent. So align the DSCI handling with what we already do for devices with multiple Input Queues: clear it right away while processing the IRQ. For the non-polling path this means that we no longer need to handle the 1-queue case separately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upper-layer drivers allocate their SBALs by calling qdio_alloc_buffers() for each individual queue. But when later passing the SBAL addresses to qdio_establish(), they need to be in a single array of pointers. So if the driver uses multiple Input or Output queues, it needs to allocate a temporary array just to present all its SBAL pointers in this layout. This patch slightly changes the format of the QDIO initialization data, so that drivers can pass a per-queue array where each element points to a queue's SBAL array. zfcp doesn't use multiple queues, so the impact there is trivial. For qeth this brings a nice reduction in complexity, and removes a page-sized allocation.

However it does provide maintenance cost and breaks from time to time. Therefore remove it. CONFIG_NUMA is still supported with a very small backend and only one node. This way userspace applications which require NUMA interfaces continue to work. Note that NODES_SHIFT is set to 1 (= 2 nodes) instead of 0 (= 1 node), since there is quite a bit of kernel code which assumes that more than one node is possible if CONFIG_NUMA is enabled.

Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Currently (because irq_ptr->debugfs_dev gets set to NULL on error) the files would be placed into the debugfs root - without any association to their parent device. On teardown, use the debugfs_remove_recursive() helper to avoid keeping track of each created file/directory.
