* 9p/trans_fd: split into dedicated moduleThomas Weißschuh2022-01-101-0/+7

* IB: Revert "remove redundant INFINIBAND kconfig dependencies"Arnd Bergmann2018-05-281-1/+1
| | | | | | | | | | | | | | | | | | | | | Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a link error when another driver using it is built-in. The INFINIBAND_ADDR_TRANS dependency is insufficient here as this is a 'bool' symbol that does not force anything to be a module in turn. fs/cifs/smbdirect.o: In function `smbd_disconnect_rdma_work': smbdirect.c:(.text+0x1e4): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_request': trans_rdma.c:(.text+0x7bc): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_destroy_trans': trans_rdma.c:(.text+0x830): undefined reference to `ib_destroy_qp' trans_rdma.c:(.text+0x858): undefined reference to `ib_dealloc_pd' Fixes: 9533b292a7ac ("IB: remove redundant INFINIBAND kconfig dependencies") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Greg Thelen <gthelen@google.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
* IB: remove redundant INFINIBAND kconfig dependenciesGreg Thelen2018-05-091-1/+1
| | | | | | | | | INFINIBAND_ADDR_TRANS depends on INFINIBAND. So there's no need for options which depend INFINIBAND_ADDR_TRANS to also depend on INFINIBAND. Remove the unnecessary INFINIBAND depends. Signed-off-by: Greg Thelen <gthelen@google.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

* net/9p: remove depends on CONFIG_EXPERIMENTALKees Cook2013-01-111-1/+1
| | | | | | | | | | The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default.

* 9p: remove experimental tag from tested configurationsEric Van Hensbergen2011-05-251-4/+4
| | | | | | | | | The 9p client is currently undergoing regular regresssion and stress testing as a by-product of the virtfs work. I think its finally time to take off the experimental tags from the well-tested code paths. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: disallow RDMA if RDMA CM isn't availableRoland Dreier2009-01-151-1/+1
| | | | | | | | | | | | | | | If INET=y and INFINIBAND=y, but IPV6=m then INFINIBAND_ADDR_TRANS is set to n and the RDMA CM functions rdma_connect() et al are not built. However, the current config dependencies allow NET_9P_RDMA to be selected in this, which leads to a build failure. Fix this by adding a dependency on INFINIBAND_ADDR_TRANS to disallow NET_9P_RDMA in this case.

* 9p: fix error path during early mountEric Van Hensbergen2008-05-141-10/+0
| | | | | | | | | | | | | There was some cleanup issues during early mount which would trigger a kernel bug for certain types of failure. This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization. Keeping the fd transport separate from the core 9pnet code seemed like a good idea at the time, but in practice has caused more harm and confusion than good.

* typo fixesMatt LaPlante2007-10-201-1/+1
| | | | | | | | | | | | Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

* 9p: Make transports dynamicEric Van Hensbergen2007-10-171-0/+10
| | | | | | | | | This patch abstracts out the interfaces to underlying transports so that new transports can be added as modules. This should also allow kernel configuration of transports without ifdef-hell. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: Reorganization of 9p file system codeLatchesar Ionkov2007-07-141-0/+21
This patchset moves non-filesystem interfaces of v9fs from fs/9p to net/9p. It moves the transport, packet marshalling and connection layers to net/9p leaving only the VFS related files in fs/9p. This work is being done in preparation for in-kernel 9p servers as well as alternate 9p clients (other than VFS).
