RDMA/restrack: Hide restrack DB from IB/core

2019-02-19T04:04:36Z

There is no need to expose internals of restrack DB to IB/core. Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/restrack: Reduce scope of synchronization lock while updating DB

2019-02-19T04:04:36Z

XArray uses internal lock for updates to XArray. This means that our external RW lock is needed to ensure that entry is not deleted while we are performing iteration over list. Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/restrack: Translate from ID to restrack object

2019-02-19T04:04:36Z

Add new general helper to get restrack entry given by ID and their respective type. Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/restrack: Convert internal DB from hash to XArray

2019-02-19T04:04:36Z

The additions of .doit callbacks posses new access pattern to the resource entries by some user visible index. Back then, the legacy DB was implemented as hash because per-index access wasn't needed and XArray wasn't accepted yet. Acceptance of XArray together with per-index access requires the refresh of DB implementation. Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/core: Use the ops infrastructure to keep all callbacks in one place

2019-01-31T04:34:21Z

As preparation to hide rdma_restrack_root, refactor the code to use the ops structure instead of a special callback which is hidden in rdma_restrack_root. Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/core: Simplify restrack interface

2019-01-31T04:15:47Z

In the current implementation, we have one restrack root per-device and all users are simply providing it directly. Let's simplify the interface and have callers provide the ib_device and internally access the restrack_root. Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/restrack: Resource-tracker should not use uobject pointers

2018-12-18T22:38:26Z

Having uobject pointer embedded in ib core objects is not aligned with a future shared ib_x model. The resource tracker only does this to keep track of user/kernel objects - track this directly instead. Signed-off-by: Shamir Rabinovitch Signed-off-by: Jason Gunthorpe

RDMA/restrack: Track ucontext

2018-12-03T19:58:25Z

Add ability to track allocated ib_ucontext, which are limited resource and worth to be visible by users. Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

RDMA/restrack: Consolidate task name updates in one place

RDMA/restrack: Un-inline set task implementation

Prepare rdma_restrack_set_task() call to accommodate more code by moving its implementation from *.h to *.c. Reviewed-by: Artemy Kovalyov Reviewed-by: Yossi Itigin Signed-off-by: Leon Romanovsky Reviewed-by: Steve Wise Signed-off-by: Jason Gunthorpe
