* uuid: hoist uuid_is_null() helper from libnvdimmChristoph Hellwig2017-06-053-8/+19
| | | | | | | | | | | | | | | | | | Hoist the libnvdimm helper as an inline helper to linux/uuid.h using an auxiliary const variable uuid_null in lib/uuid.c. [hch: also add the guid variant. Both do the same but I'd like to keep casts to a minimum] The common helper uses the new abstract type uuid_t * instead of u8 *.

* uuid: rename uuid typesChristoph Hellwig2017-06-056-62/+73
| | | | | | | | | | | | | | | | | | | | | | | | Our "little endian" UUID really is a Wintel GUID, so rename it and its helpers such (guid_t). The big endian UUID is the only true one, so give it the name uuid_t. The uuid_le and uuid_be names are retained for now, but will hopefully go away soon. The exception to that are the _cmp helpers that will be replaced by better primitives ASAP and thus don't get the new names. Also the _to_bin helpers are named to match the better named uuid_parse routine in userspace. Also remove the existing typedef in XFS that's now been superceeded by the generic type name.

* uuid,afs: move struct uuid_v1 back into afsChristoph Hellwig2017-06-054-34/+19
| | | | | | | | | | | | | | | This essentially is a partial revert of commit ff548773 ("afs: Move UUID struct to linux/uuid.h") and moves struct uuid_v1 back into fs/afs as struct afs_uuid. It however keeps it as big endian structure so that we can use the normal uuid generation helpers when casting to/from struct afs_uuid. The V1 uuid intrepretation in struct form isn't really useful to the rest of the kernel, and not really compatible to it either, so move it back to AFS instead of polluting the global uuid.h.

* fs/ufs: Set UFS default maximum bytes per fileRichard Narron2017-06-041-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem with reading files larger than 2GB from a UFS-2 file system: https://bugzilla.kernel.org/show_bug.cgi?id=195721 The incorrect UFS s_maxsize limit became a problem as of commit c2a9737f45e2 ("vfs,mm: fix a dead loop in truncate_inode_pages_range()") which started using s_maxbytes to avoid a page index overflow in do_generic_file_read(). That caused files to be truncated on UFS-2 file systems because the default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it. Here I simply increase the default to a common value used by other file systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you attempt a TCP mount from an host that is unreachable in a way that triggers an immediate error from kernel_connect(), that error does not propagate up, instead EAGAIN is reported. This results in call_connect_status receiving the wrong error. A case that it easy to demonstrate is to attempt to mount from an address that results in ENETUNREACH, but first deleting any default route. Without this patch, the mount.nfs process is persistently runnable and is hard to kill. With this patch it exits as it should. The problem is caused by the fact that xs_tcp_force_close() eventually calls xprt_wake_pending_tasks(xprt, -EAGAIN); which causes an error return of -EAGAIN. so when xs_tcp_setup_sock() calls xprt_wake_pending_tasks(xprt, status); the status is ignored.

| * pnfs: Fix the check for requests in range of layout segmentBenjamin Coddington2017-05-242-8/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible and acceptable for NFS to attempt to add requests beyond the range of the current pgio->pg_lseg, a case which should be caught and limited by the pg_test operation. However, the current handling of this case replaces pgio->pg_lseg with a new layout segment (after a WARN) within that pg_test operation. That will cause all the previously added requests to be submitted with this new layout segment, which may not be valid for those requests. Fix this problem by only returning zero for the number of bytes to coalesce from pg_test for this case which allows any previously added requests to complete on the current layout segment. The check for requests starting out of range of the layout segment moves to pg_init, so that the replacement of pgio->pg_lseg will be done when the next request is added.

Testing + comparing DSDTs has shown that this only happens on Cherry Trail devices with an AXP288 PMIC, the AXP288 PMIC is also used on Bay Trail devices but there the power button is only connected to the PMIC and not handled by soc_button_array. This means that the INTCFD9 check has caused a regression on Bay Trail devices, causing power-button presses to no longer be seen. This commit fixes this by limiting the check to devices where the ACPI node for the AXP288 contains a _HRV (hardware revision) attribute with a value of 3 which indicates we are dealing with a Cherry Trail platform.

Its purpose is to keep data synced between CPU and DMA device when swapping happens after mem deregistration ops. Now we choose not to set page dirty bit if it's already set by kernel prior to calling __ib_umem_release(). This reduces memory deregistration time by half or even more when we ran application simulation test program.

This produces the following sparse warning: drivers/infiniband/core/uverbs_marshall.c:99:6: warning: symbol '__ib_copy_path_rec_to_user' was not declared. Should it be static? In addition, it used sizeof ... notations instead of sizeof(...), which is correct in C, but a little bit misleading. Let's change it too.

Let's remove EXPORT_SYMBOL from ibnl_chk_listeners() and move all these functions to private header file.
