From: Olaf Hering <olh@suse.de> ext3 as module is not possible in 2.6.6, clear_pages, called from clear_page, is not exported. Also, unexport clear_page(), which is an inline.

Jorn Engel <joern@wohnheim.fh-wedel.de> inode->i_flags should never contain fs-specific flags. In fact, it doesn't; the checks against it cause "chattr +T" to be useless for ext[23]. Same bug was in befs as well.

From: "Sergey S. Kostyliov" <rathamahata@php4.ru> We already have block number (inode->i_ino), so there is no need to calculate it from befs_block_run before sb_bread() call (this is what befs_bread_iaddr() do).

Andrew Morton authored
From: "Sergey S. Kostyliov" <rathamahata@php4.ru> LBD patch merged long time ago, so it is safe to pass u64 block numbers to sb_bread() when sector_t is large enough.

From: Geoff Gustafson <geoff@linux.jf.intel.com>, "Chen, Kenneth W" <kenneth.w.chen@intel.com>, Ingo Molnar <mingo@elte.hu>, me. The big-SMP guys are seeing high CPU load due to del_timer_sync()'s inefficiencies. The callers are fs/aio.c and schedule_timeout(). We note that neither of these callers' timer handlers actually re-add the timer - they are single-shot. So we don't need all that complexity in del_timer_sync() - we can just run del_timer() and if that worked we know the timer is dead. Add del_single_shot_timer(), export it to modules and use it in AIO and schedule_timeout(). (these numbers are for an earlier patch, but they'll be close) Before: 32p 4p Warm cache 29,000 505 Cold cache 37,800 1220 After: 32p 4p Warm cache 95 88 Cold cache 1,800 140 [Measurements are CPU cycles spent in a call to del_timer_sync, the average of 1000 calls. 32p is 16-node NUMA, 4p is SMP.] (I cleaned up a few things and added some commentary)

Lookup typically touches three fields of the dentry: d_bucket, d_name.hash and d_parent. Change the layout of things so that these will always be in the same cacheline.

- d_vfs_flags can be removed - just use d_flags. All modifications of dentry->d_flags are under dentry->d_lock. On x86 this takes the internal string size up to 40 bytes. The internal/external ratio on my 1.5M files hits 96%.
-
Andrew Morton authored
The gap between checking d_bucket and sampling d_move_count looks like a bug to me. It feels safer to be checking d_bucket after taking the lock, when we know that it is stable. And it's a little faster to check d_bucket after having checked the hash rather than before.
-
Andrew Morton authored
When dentries are given an external name we currently allocate an entire qstr for the external name. This isn't needed. We can use the internal qstr and kmalloc only the string itself. This saves 12 bytes from externally-allocated names and 4 bytes from the dentry itself. The saving of 4 bytes from the dentry doesn't actually decrease the dentry's storage requirements, but it makes four more bytes available for internal names, taking the internal/external ratio from 89% up to 93% on my 1.5M files. Fix: The qstr consolidation wasn't quite right, because it can cause qstr->len to be unstable during lookup lockless traverasl. Fix that up by taking d_lock earlier in lookup. This serialises against d_move. Take the lock after comparing the parent and hash to preserve the mostly-lockless behaviour. This obsoletes d_movecount, which is removed.

Rework dentries so that the inline name length is between 31 and 48 bytes. On SMP P4-compiled x86 each dentry consumes 160 bytes (24 per page). Here's the histogram of name lengths on all 1.5M files on my workstation: 1: 0% 2: 0% 3: 1% 4: 5% 5: 8% 6: 13% 7: 19% 8: 26% 9: 33% 10: 42% 11: 49% 12: 55% 13: 60% 14: 64% 15: 67% 16: 69% 17: 71% 18: 73% 19: 75% 20: 76% 21: 78% 22: 79% 23: 80% 24: 81% 25: 82% 26: 83% 27: 85% 28: 86% 29: 87% 30: 88% 31: 89% 32: 90% 33: 91% 34: 92% 35: 93% 36: 94% 37: 95% 38: 96% 39: 96% 40: 96% 41: 96% 42: 96% 43: 96% 44: 97% 45: 97% 46: 97% 47: 97% 48: 97% 49: 98% 50: 98% 51: 98% 52: 98% 53: 98% 54: 98% 55: 98% 56: 98% 57: 98% 58: 98% 59: 98% 60: 99% 61: 99% 62: 99% 63: 99% 64: 99% So on x86 we'll fit 89% of filenames into the inline name. The patch also removes the NAME_ALLOC_LEN() rounding-up of the storage for the out-of-line names. That seems unnecessary.

Be consistent about d_vfs_flags locking: take dentry->d_lock when modifying it.
-
Andrew Morton authored
A few filesystems modify dentry.d_flags under non-obvious locking. To consolidate that field wth d_vfs_flags they need to take ->d_lock

From: Markus Lidel <Markus.Lidel@shadowconnect.com> * The Kconfig and Makefile in drivers/message/i2o still got a CONFIG_I2O_PCI entry, which is not used anymore. This one is replaced by a CONFIG_I2O_CONFIG entry, which now builds the i2o_config module.

From: Markus Lidel <Markus.Lidel@shadowconnect.com> * provides i2o_context_list_*() functions, which maps 64-bit pointers to 32-bit context id's in a dynamic list. On 32-bit systems the functions are replaced with a static inline. * i2o_scsi now uses the i2o_context_list_*() functions for transaction context, and therefore now work on 64-bit systems too.

From: Markus Lidel <Markus.Lidel@shadowconnect.com> * more than 3 "visible" disks (hda, hdb, hdc, hdd) lead to kernel panics. * removes some unused code with partitions. * I2O_LOCK was often called with the addresses of the controller, and not with the address of the device. Fixed. * the cleanup function for gendisk (del_gendisk) doesn't work if the queue is shared between different devices. To workaround the queue is removed before. * redundant code removed in module initialization and remove, use i2ob_new_device and i2ob_del_device instead. * removed atomic_t queue_depth * removed unnecessary and bogus code for queue handling

From: Ashok Raj <ashok.raj@intel.com> Supports basic ability to enable hotplug functions for IA64. Code is just evolving, and there are several loose ends to tie up. What this code drop does - Support logical online and offline - Handles interrupt migration without loss of interrupts. - Handles stress fine > 24+ hrs with make -j/ftp/rcp workloads - Handles irq migration from a dying cpu without loss of interrupts. What needs to be done - Boot CPU removal support, with platform level authentication - Putting cpu being removed in BOOT_RENDEZ mode.
