* nfs: remove the objlayout driverChristoph Hellwig2017-04-209-2033/+0

* NFSv4: Fix a hang in OPEN related to server rebootTrond Myklebust2017-04-201-1/+3
| | | | | | | | | | | | If the server fails to return the attributes as part of an OPEN reply, and then reboots, we can end up hanging. The reason is that the client attempts to send a GETATTR in order to pick up the missing OPEN call, but fails to release the slot first, causing reboot recovery to deadlock.

* NFS: Fix missing pg_cleanup after nfs_pageio_cond_complete()Benjamin Coddington2017-04-201-2/+4
| | | | | | | | | | | | | | Commit a7d42ddb3099727f58366fa006f850a219cce6c8 ("nfs: add mirroring support to pgio layer") moved pg_cleanup out of the path when there was non-sequental I/O that needed to be flushed. The result is that for layouts that have more than one layout segment per file, the pg_lseg is not cleared, so we can end up hitting the WARN_ON_ONCE(req_start >= seg_end) in pnfs_generic_pg_test since the pg_lseg will be pointing to that previously-flushed layout segment.

* sunrpc: don't check for failure from mempool_alloc()NeilBrown2017-04-202-13/+0
| | | | | | | | | | | | When mempool_alloc() is allowed to sleep (GFP_NOIO allows sleeping) it cannot fail. So rpc_alloc_task() cannot fail, so rpc_new_task doesn't need to test for failure. Consequently rpc_new_task() cannot fail, so the callers don't need to test. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
* NFS: fix usage of mempools.NeilBrown2017-04-203-26/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When passed GFP flags that allow sleeping (such as GFP_NOIO), mempool_alloc() will never return NULL, it will wait until memory is available. This means that we don't need to handle failure, but that we do need to ensure one thread doesn't call mempool_alloc() twice on the one pool without queuing or freeing the first allocation. If multiple threads did this during times of high memory pressure, the pool could be exhausted and a deadlock could result. pnfs_generic_alloc_ds_commits() attempts to allocate from the nfs_commit_mempool while already holding an allocation from that pool. This is not safe. So change nfs_commitdata_alloc() to take a flag that indicates whether failure is acceptable. In pnfs_generic_alloc_ds_commits(), accept failure and handle it as we currently do. Else where, do not accept failure, and do not handle it. Even when failure is acceptable, we want to succeed if possible. That means both - using an entry from the pool if there is one - waiting for direct reclaim is there isn't. We call mempool_alloc(GFP_NOWAIT) to achieve the first, then kmem_cache_alloc(GFP_NOIO|__GFP_NORETRY) to achieve the second. Each of these can fail, but together they do the best they can without blocking indefinitely. The objects returned by kmem_cache_alloc() will still be freed by mempool_free(). This is safe as mempool_alloc() uses exactly the same function to allocate objects (since the mempool was created with mempool_create_slab_pool()). The object returned by mempool_alloc() and kmem_cache_alloc() are indistinguishable so mempool_free() will handle both identically, either adding to the pool or calling kmem_cache_free(). Also, don't test for failure when allocating from nfs_wdata_mempool. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

* NFS: switch back to to ->iterate()Benjamin Coddington2017-04-201-25/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFS has some optimizations for readdir to choose between using READDIR or READDIRPLUS based on workload, and which NFS operation to use is determined by subsequent interactions with lookup, d_revalidate, and getattr. Concurrent use of nfs_readdir() via ->iterate_shared() can cause those optimizations to repeatedly invalidate the pagecache used to store directory entries during readdir(), which causes some very bad performance for directories with many entries (more than about 10000). There's a couple ways to fix this in NFS, but no fix would be as simple as going back to ->iterate() to serialize nfs_readdir(), and neither fix I tested performed as well as going back to ->iterate(). The first required taking the directory's i_lock for each entry, with the result of terrible contention. The second way adds another flag to the nfs_inode, and so keeps the optimizations working for large directories. The difference from using ->iterate() here is that much more memory is consumed for a given workload without any performance gain. The workings of nfs_readdir() are such that concurrent users are serialized within read_cache_page() waiting to retrieve pages of entries from the server. By serializing this work in iterate_dir() instead, contention for cache pages is reduced. Waiting processes can have an uncontended pass at the entirety of the directory's pagecache once previous processes have completed filling it. v2 - Keep the bits needed for parallel lookup Signed-off-by: Benjamin Coddington <bcodding@redhat.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

Certain OMAP devices make use of "ti,no-idle-on-init" flag which causes omap_device_enable to be called during the BUS_NOTIFY_ADD_DEVICE event during probe, along with pm_runtime_set_active. This call to pm_runtime_set_active typically will prevent a call to pm_runtime_get in a driver probe function from re-enabling the omap_device. However, in the case of a probe defer that happens before the driver probe function is able to run, such as a missing pinctrl states defer, pm_runtime_reinit will set the device as RPM_SUSPENDED and then once driver probe is actually able to run, pm_runtime_get will see the device as suspended and call through to the omap_device layer, attempting to enable the already enabled omap_device and causing errors like this: omap-gpmc 50000000.gpmc: omap_device: omap_device_enable() called from invalid state 1 omap-gpmc 50000000.gpmc: use pm_runtime_put_sync_suspend() in driver? We can avoid this error by making sure the pm_runtime status of a device matches the omap_device state before a probe attempt. By extending the omap_device bus notifier to act on the BUS_NOTIFY_BIND_DRIVER event we can check if a device is enabled in omap_device but with a pm_runtime status of RPM_SUSPENDED and once again mark the device as RPM_ACTIVE to avoid a second incorrect call to omap_device_enable.

This caused issues on some systems. We should only reset CPU1 as a last resort option, and try to avoid it where possible. Doing an unconditional CPU1 reset causes issues for example when booting a bootloader configured secure OS running on CPU1 as reported by Andrew F. Davis <afd@ti.com>. We can't completely remove the reset of CPU1 as it would break kexec booting from older kernels. But we can limit the CPU1 reset to cases where CPU1 is wrongly parked within the memory area used by the booting kernel. Then later on we can add support for parking CPU1 for kexec out of the SDRAM back to bootrom. So let's first fix the regression reported by Andrew by making CPU1 reset conditional. To do this, we need to: 1. Save configured AUX_CORE_BOOT_1 for later 2. Modify AUX_CORE_BOOT_0 reading code to for HS SoCs to return the whole register instead of the CPU mask 3. Check if CPU1 is wrongly parked into the booting kernel by the previous kernel and reset if needed Fixes: 3251885285e1 ("ARM: OMAP4+: Reset CPU1 properly for kexec") Reported-by: Andrew F.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The manufacturing information is stored in the EEPROM. This chip is an AT24C64 not not (nor has it ever been) 24C02. This patch will correctly address the EEPROM to read the entire contents and not just 256 bytes (of 0xff).
