* fs: do not assign default i_ino in new_inodeChristoph Hellwig2010-10-2631-2/+36
| | | | | | | | | | | | | | | Instead of always assigning an increasing inode number in new_inode move the call to assign it into those callers that actually need it. For now callers that need it is estimated conservatively, that is the call is added to all filesystems that do not assign an i_ino by themselves. For a few more filesystems we can avoid assigning any inode number given that they aren't user visible, and for others it could be done lazily when an inode number is actually needed, but that's left for later patches.

* fs: introduce a per-cpu last_ino allocatorEric Dumazet2010-10-261-7/+38
| | | | | | | | | | | | | | | | | new_inode() dirties a contended cache line to get increasing inode numbers. This limits performance on workloads that cause significant parallel inode allocation. Solve this problem by using a per_cpu variable fed by the shared last_ino in batches of 1024 allocations. This reduces contention on the shared last_ino, and give same spreading ino numbers than before (i.e. same wraparound after 2^32 allocations).

| | | | | | | | | | | | | Split up inode_add_to_list/__inode_add_to_list. Locking for the two lists will be split soon so these helpers really don't buy us much anymore. The __ prefixes for the sb list helpers will go away soon, but until inode_lock is gone we'll need them to distinguish between the locked and unlocked variants.

* fs: Implement lazy LRU updates for inodesNick Piggin2010-10-264-41/+71
| | | | | | | | | | | | | | | | | | | | | Convert the inode LRU to use lazy updates to reduce lock and cacheline traffic. We avoid moving inodes around in the LRU list during iget/iput operations so these frequent operations don't need to access the LRUs. Instead, we defer the refcount checks to reclaim-time and use a per-inode state flag, I_REFERENCED, to tell reclaim that iget has touched the inode in the past. This means that only reclaim should be touching the LRU with any frequency, hence significantly reducing lock acquisitions and the amount contention on LRU updates. This also removes the inode_in_use list, which means we now only have one list for tracking the inode LRU status. This makes it much simpler to split out the LRU list operations under it's own lock.

* fs: Convert nr_inodes and nr_unused to per-cpu countersDave Chinner2010-10-265-25/+52
| | | | | | | | | | | | | | | | | | The number of inodes allocated does not need to be tied to the addition or removal of an inode to/from a list. If we are not tied to a list lock, we could update the counters when inodes are initialised or destroyed, but to do that we need to convert the counters to be per-cpu (i.e. independent of a lock). This means that we have the freedom to change the list/locking implementation without needing to care about the counters. Based on a patch originally from Eric Dumazet.

* aio: bump i_count instead of using igrabChris Mason2010-10-261-1/+14
| | | | | | | | | | | | | | | | The aio batching code is using igrab to get an extra reference on the inode so it can safely batch. igrab will go ahead and take the global inode spinlock, which can be a bottleneck on large machines doing lots of AIO. In this case, igrab isn't required because we already have a reference on the file handle. It is safe to just bump the i_count directly on the inode. Benchmarking shows this patch brings IOP/s on tons of flash up by about 2.5X. Signed-off-by: Chris Mason <chris.mason@oracle.com>

Note : /proc/sys/fs/file-nr is a read-only file, so this patch doesnt depend on previous patch (sysctl: fix min/max handling in __do_proc_doulongvec_minmax()) Thanks ! [PATCH V4] fs: allow for more than 2^31 files Robin Holt tried to boot a 16TB system and found af_unix was overflowing a 32bit value : <quote> We were seeing a failure which prevented boot. The kernel was incapable of creating either a named pipe or unix domain socket. This comes down to a common kernel function called unix_create1() which does: atomic_inc(&unix_nr_socks); if (atomic_read(&unix_nr_socks) > 2 * get_max_files()) goto out; The function get_max_files() is a simple return of files_stat.max_files. files_stat.max_files is a signed integer and is computed in fs/file_table.c's files_init(). n = (mempages * (PAGE_SIZE / 1024)) / 10; files_stat.max_files = n; In our case, mempages (total_ram_pages) is approx 3,758,096,384 (0xe0000000). That leaves max_files at approximately 1,503,238,553. This causes 2 * get_max_files() to integer overflow. </quote> Fix is to let /proc/sys/fs/file-nr & /proc/sys/fs/file-max use long integers, and change af_unix to use an atomic_long_t instead of atomic_t. get_max_files() is changed to return an unsigned long. get_nr_files() is changed to return a long. unix_nr_socks is changed from atomic_t to atomic_long_t, while not strictly needed to address Robin problem.
