When running the SPECint_rate gcc on some very large boxes it was noticed that the system was spending lots of time in mpol_shared_policy_lookup(). The gamess benchmark can also show it and is what I mostly used to chase down the issue since the setup for that I found to be easier. To be clear the binaries were on tmpfs because of disk I/O requirements. We then used text replication to avoid icache misses and having all the copies banging on the memory where the instruction code resides. This results in us hitting a bottleneck in mpol_shared_policy_lookup() since lookup is serialised by the shared_policy lock. I have only reproduced this on very large (3k+ cores) boxes. The problem starts showing up at just a few hundred ranks getting worse until it threatens to livelock once it gets large enough. For example on the gamess benchmark at 128 ranks this area consumes only ~1% of time, at 512 ranks it consumes nearly 13%, and at 2k ranks it is over 90%. To alleviate the contention in this area I converted the spinlock to an rwlock. This allows a large number of lookups to happen simultaneously. The results were quite good reducing this consumtion at max ranks to around 2%. [akpm@linux-foundation.org: tidy up code comments] Signed-off-by:

Mark those kmem allocations that are known to be easily triggered from userspace as __GFP_ACCOUNT/SLAB_ACCOUNT, which makes them accounted to memcg. For the list, see below: - threadinfo - task_struct - task_delay_info - pid - cred - mm_struct - vm_area_struct and vm_region (nommu) - anon_vma and anon_vma_chain - signal_struct - sighand_struct - fs_struct - files_struct - fdtable and fdtable->full_fds_bits - dentry and external_name - inode for all filesystems. This is the most tedious part, because most filesystems overwrite the alloc_inode method. The list is far from complete, so feel free to add more objects. Nevertheless, it should be close to "account everything" approach and keep most workloads within bounds. Malevolent users will be able to breach the limit, but this was possible even with the former "account everything" approach (simply because it did not account everything in fact).

Vladimir Davydov authored
Currently, if we want to account all objects of a particular kmem cache, we have to pass __GFP_ACCOUNT to each kmem_cache_alloc call, which is inconvenient. This patch introduces SLAB_ACCOUNT flag which if passed to kmem_cache_create will force accounting for every allocation from this cache even if __GFP_ACCOUNT is not passed. This patch does not make any of the existing caches use this flag - it will be done later in the series. Note, a cache with SLAB_ACCOUNT cannot be merged with a cache w/o SLAB_ACCOUNT, because merged caches share the same kmem_cache struct and hence cannot have different sets of SLAB_* flags. Thus using this flag will probably reduce the number of merged slabs even if kmem accounting is not used (only compiled in). Signed-off-by:

Black-list kmem accounting policy (aka __GFP_NOACCOUNT) turned out to be fragile and difficult to maintain, because there seem to be many more allocations that should not be accounted than those that should be. Besides, false accounting an allocation might result in much worse consequences than not accounting at all, namely increased memory consumption due to pinned dead kmem caches. So this patch switches kmem accounting to the white-policy: now only those kmem allocations that are marked as __GFP_ACCOUNT are accounted to memcg. Currently, no kmem allocations are marked like this. The following patches will mark several kmem allocations that are known to be easily triggered from userspace and therefore should be accounted to memcg. Signed-off-by:

Currently, all kmem allocations (namely every kmem_cache_alloc, kmalloc, alloc_kmem_pages call) are accounted to memory cgroup automatically. Callers have to explicitly opt out if they don't want/need accounting for some reason. Such a design decision leads to several problems: - kmalloc users are highly sensitive to failures, many of them implicitly rely on the fact that kmalloc never fails, while memcg makes failures quite plausible. - A lot of objects are shared among different containers by design. Accounting such objects to one of containers is just unfair. Moreover, it might lead to pinning a dead memcg along with its kmem caches, which aren't tiny, which might result in noticeable increase in memory consumption for no apparent reason in the long run. - There are tons of short-lived objects. Accounting them to memcg will only result in slight noise and won't change the overall picture, but we still have to pay accounting overhead. For more info, see - http://lkml.kernel.org/r/20151105144002.GB15111%40dhcp22.suse.cz - http://lkml.kernel.org/r/20151106090555.GK29259@esperanza Therefore this patchset switches to the white list policy. Now kmalloc users have to explicitly opt in by passing __GFP_ACCOUNT flag. Currently, the list of accounted objects is quite limited and only includes those allocations that (1) are known to be easily triggered from userspace and (2) can fail gracefully (for the full list see patch no. 6) and it still misses many object types. However, accounting only those objects should be a satisfactory approximation of the behavior we used to have for most sane workloads. This patch (of 6): Revert 499611ed ("kernfs: do not account ino_ida allocations to memcg"). Black-list kmem accounting policy (aka __GFP_NOACCOUNT) turned out to be fragile and difficult to maintain, because there seem to be many more allocations that should not be accounted than those that should be. Besides, false accounting an allocation might result in much worse consequences than not accounting at all, namely increased memory consumption due to pinned dead kmem caches.

In ocfs2_orphan_del, currently it finds and deletes entry first, and then access orphan dir dinode. This will have a problem once ocfs2_journal_access_di fails. In this case, entry will be removed from orphan dir, but in deed the inode hasn't been deleted successfully. In other words, the file is missing but not actually deleted. So we should access orphan dinode first like unlink and rename. Signed-off-by:

The following case will lead to slot overwritten. N1 N2 mount ocfs2 volume, find and allocate slot 0, then set osb->slot_num to 0, begin to write slot info to disk mount ocfs2 volume, wait for super lock write block fail because of storage link down, unlock super lock got super lock and also allocate slot 0 then unlock super lock mount fail and then dismount, since osb->slot_num is 0, try to put invalid slot to disk. And it will succeed if storage link restores. N2 slot info is now overwritten Once another node say N3 mount, it will find and allocate slot 0 again, which will lead to mount hung because journal has already been locked by N2. so when write slot info failed, invalidate slot in advance to avoid overwrite slot.

Commit f3f85464 ("ocfs2_dlm: Ensure correct ordering of set/clear refmap bit on lockres") still exists a race which can't ensure the ordering is exactly correct. Node1 Node2 Node3 umount, migrate lockres to Node2 migrate finished, send migrate request to Node3 received migrate request, create a migration_mle, respond to Node2. set DLM_LOCK_RES_SETREF_INPROG and send assert master to Node3 delete migration_mle in assert_master_handler, Node3 umount without response dlm_thread purge this lockres, send drop deref message to Node2 found the flag of DLM_LOCK_RES_SETREF_INPROG is set, dispatch dlm_deref_lockres_worker to clear refmap, but in function of dlm_deref_lockres_worker, only if node in refmap it wait DLM_LOCK_RES_SETREF_INPROG to be cleared. So worker is done successfully purge lockres, send assert master response to Node1, and finish umount set Node3 in refmap, and it won't be cleared forever, thus lead to umount hung so wait until DLM_LOCK_RES_SETREF_INPROG is cleared in dlm_deref_lockres_worker.

Commit ac551828 ("modpost: i2c aliases need no trailing wildcard") removed the wildcard at the end of the I2C module aliases because I2C devices have no IDs so the aliases are just arbitrary device names. This is also true for OF modaliases since a compatible string is used to define a specific IP hardware block. So the modalias should match a specific compatible string and not attempt to match a compatible string whose name matches the beginning of another one. For example, the following driver module: $ modinfo cros_ec_keyb | grep alias alias: platform:cros-ec-keyb alias: of:N*T*Cgoogle,cros-ec-keyb* will be tried to be loaded for an alias of:N*T*Cgoogle,cros-ec-keyb-v2 but there could be a different driver that supports the device for that compatible string so it's better to remove the trailing wildcard for OF. Also, remove the word "always" from the add_wildcard() function comment since that was carried from the time where a wildcard was always added at the end of the module alias for all the devices.

At the time that this code was originally written, call_srcu didn't exist, so this thread was required to ensure that we waited for that SRCU grace period to settle before finally freeing the object. It does exist now however and we can much more efficiently use call_srcu to handle this. That also allows us to potentially use srcu_barrier to ensure that they are all of the callbacks have run before proceeding. In order to conserve space, we union the rcu_head with the g_list. This will be necessary for nfsd which will allocate marks from a dedicated slabcache. We have to be able to ensure that all of the objects are destroyed before destroying the cache.
