* NFSv4: Ensure that we call FREE_STATEID when NFSv4.x stateids are revokedTrond Myklebust2014-11-122-11/+0Star
| | | | | | | | | NFSv4.x (x>0) requires us to call TEST_STATEID+FREE_STATEID if a stateid is revoked. We will currently fail to do this if the stateid is a delegation. http://lkml.kernel.org/r/CAN-5tyHwG=Cn2Q9KsHWadewjpTTy_K26ee+UnSvHvG4192p-Xw@mail.gmail.com Cc: stable@vger.kernel.org Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
* NFSv4: Fix races between nfs_remove_bad_delegation() and delegation returnTrond Myklebust2014-11-123-3/+23
| | | | | | | | | | | | | | | | | Any attempt to call nfs_remove_bad_delegation() while a delegation is being returned is currently a no-op. This means that we can end up looping forever in nfs_end_delegation_return() if something causes the delegation to be revoked. This patch adds a mechanism whereby the state recovery code can communicate to the delegation return code that the delegation is no longer valid and that it should not be used when reclaiming state. It also changes the return value for nfs4_handle_delegation_recall_error() to ensure that nfs_end_delegation_return() does not reattempt the lock reclaim before state recovery is done. http://lkml.kernel.org/r/CAN-5tyHwG=Cn2Q9KsHWadewjpTTy_K26ee+UnSvHvG4192p-Xw@mail.gmail.com Cc: stable@vger.kernel.org Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
* NFSv4.1: nfs41_clear_delegation_stateid shouldn't trust NFS_DELEGATED_STATETrond Myklebust2014-11-121-25/+17Star
| | | | | | | | | | | | | | | | | | This patch removes the assumption made previously, that we only need to check the delegation stateid when it matches the stateid on a cached open. If we believe that we hold a delegation for this file, then we must assume that its stateid may have been revoked or expired too. If we don't test it then our state recovery process may end up caching open/lock state in a situation where it should not. We therefore rename the function nfs41_clear_delegation_stateid as nfs41_check_delegation_stateid, and change it to always run through the delegation stateid test and recovery process as outlined in RFC5661. http://lkml.kernel.org/r/CAN-5tyHwG=Cn2Q9KsHWadewjpTTy_K26ee+UnSvHvG4192p-Xw@mail.gmail.com Cc: stable@vger.kernel.org Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
* NFSv4: Ensure that we remove NFSv4.0 delegations when state has expiredTrond Myklebust2014-11-121-1/+23
| | | | | | | | | | NFSv4.0 does not have TEST_STATEID/FREE_STATEID functionality, so unlike NFSv4.1, the recovery procedure when stateids have expired or have been revoked requires us to just forget the delegation. http://lkml.kernel.org/r/CAN-5tyHwG=Cn2Q9KsHWadewjpTTy_K26ee+UnSvHvG4192p-Xw@mail.gmail.com Cc: stable@vger.kernel.org Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

* nfs: fix pnfs direct write memory leakPeng Tao2014-11-122-0/+12
| | | | | | | | | | | | | For pNFS direct writes, layout driver may dynamically allocate ds_cinfo.buckets. So we need to take care to free them when freeing dreq. Ideally this needs to be done inside layout driver where ds_cinfo.buckets are allocated. But buckets are attached to dreq and reused across LD IO iterations. So I feel it's OK to free them in the generic layer.

| | | | | | | | | | If the OPEN rpc call to the server fails with an ENOENT call, nfs_atomic_open will create a negative dentry for that file, however it currently fails to call nfs_set_verifier(), thus causing the dentry to be immediately revalidated on the next call to nfs_lookup_revalidate() instead of following the usual lookup caching rules.

With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering. Use deferred probing so that the new link order (in 3.18-rc) can still allow for successful probing. - Fix suspend/resume support for LH28F640BF NOR flash" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After '#echo mem > /sys/power/state' some devices can not be properly resumed because apparently the MTD Partition Configuration Register has been reset to default thus the rootfs cannot be mounted cleanly on resume. An example of this can be found in the SA-1100 Developer's Manual at 9.5.3.3 where the second step of the Sleep Shutdown Sequence is described: "An internal reset is applied to the SA-1100. All units are reset...". As workaround we refresh the PCR value as done initially on chip setup. This behavior and the fix are confirmed by our tests done on 2 different Zaurus collie units with kernel 3.17.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | m25p80's device ID table is now spi_nor_ids, defined in spi-nor. The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hash key computation in vmw_cmdbuf_res_remove incorrectly didn't take the resource type into account, contrary to all the other related functions. This becomes important when the cmdbuf resource manager handles more than one resource type. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Brian Paul <brianp@vmware.com>

So dropping/reaquiring the lock via drm_modeset_(un)lock() directly isn't the right thing to do, as lockdep kindly points out. The 'FIXME's about sorting out whether vmwgfx *really* needs to lock-all for cursor updates still apply.
