There are currently various laptop drivers floating about with no central place for their documentation, which is currently scattered around the top level Documentation/ directory.

Following the deprecation schedule the a.out ELF interpreter support is removed now with this patch. a.out ELF interpreters were an transition feature for moving a.out systems to ELF, but they're unlikely to be still needed. Pure a.out systems will still work of course. This allows to simplify the hairy ELF loader.

2008-02-08mount options: add documentationMiklos Szeredi1-3/+47
This series addresses the problem of showing mount options in /proc/mounts. Several filesystems which use mount options, have not implemented a .show_options superblock operation. Several others have implemented this callback, but have not kept it fully up to date with the parsed options. Q: Why do we need correct option showing in /proc/mounts? A: We want /proc/mounts to fully replace /etc/mtab. The reasons for this are: - unprivileged mounters won't be able to update /etc/mtab - /etc/mtab doesn't work with private mount namespaces - /etc/mtab can become out-of-sync with reality Q: Can't this be done, so that filesystems need not bother with implementing a .show_mounts callback, and keeping it up to date? A: Only in some cases. Certain filesystems allow modification of a subset of options in their remount_fs method. It is not possible to take this into account without knowing exactly how the filesystem handles options. For the simple case (no remount or remount resets all options) the patchset introduces two helpers: generic_show_options() save_mount_options() These can also be used to emulate the old /etc/mtab behavior, until proper support is added. Even if this is not 100% correct, it's still better than showing no options at all.

2008-02-08aoe: user can ask driver to forget previously detected devicesEd L. Cashin2-0/+3
When an AoE device is detected, the kernel is informed, and a new block device is created. If the device is unused, the block device corresponding to remote device that is no longer available may be removed from the system by telling the aoe driver to "flush" its list of devices. Without this patch, software like GPFS and LVM may attempt to read from AoE devices that were discovered earlier but are no longer present, blocking until the I/O attempt times out.

SLUB: Deal with annoying gcc warning on kfree()
2008-02-08SLUB: Support for performance statisticsChristoph Lameter1-11/+138
The statistics provided here allow the monitoring of allocator behavior but at the cost of some (minimal) loss of performance. Counters are placed in SLUB's per cpu data structure. The per cpu structure may be extended by the statistics to grow larger than one cacheline which will increase the cache footprint of SLUB. There is a compile option to enable/disable the inclusion of the runtime statistics and its off by default. The slabinfo tool is enhanced to support these statistics via two options: -D Switches the line of information displayed for a slab from size mode to activity mode. -A Sorts the slabs displayed by activity. This allows the display of the slabs most important to the performance of a certain load. -r Report option will report detailed statistics on Example (tbench load): slabinfo -AD ->Shows the most active slabs Name Objects Alloc Free %Fast skbuff_fclone_cache 33 111953835 111953835 99 99 :0000192 2666 5283688 5281047 99 99 :0001024 849 5247230 5246389 83 83 vm_area_struct 1349 119642 118355 91 22 :0004096 15 66753 66751 98 98 :0000064 2067 25297 23383 98 78 dentry 10259 28635 18464 91 45 :0000080 11004 18950 8089 98 98 :0000096 1703 12358 10784 99 98 :0000128 762 10582 9875 94 18 :0000512 184 9807 9647 95 81 :0002048 479 9669 9195 83 65 anon_vma 777 9461 9002 99 71 kmalloc-8 6492 9981 5624 99 97 :0000768 258 7174 6931 58 15 So the skbuff_fclone_cache is of highest importance for the tbench load.

- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell interrupt clearance is cached - add conditional declaration for arcmsr_pci_error_detected() and arcmsr_pci_slot_reset - check if the sg list member number exceeds arcmsr default limit in arcmsr_build_ccb() - change the returned value type of arcmsr_build_ccb()from "void" to "int" returns FAILED in arcmsr_queue_command() - modify arcmsr_drain_donequeue() to ignore unknown command and let kernel process command timeout.

2008-02-07iget: remove iget() and the read_inode() super op as being obsoleteDavid Howells3-23/+9
Remove the old iget() call and the read_inode() superblock operation it uses as these are really obsolete, and the use of read_inode() does not produce proper error handling (no distinction between ENOMEM and EIO when marking an inode bad). Furthermore, this removes the temptation to use iget() to find an inode by number in a filesystem from code outside that filesystem. iget_locked() should be used instead. A new function is added in an earlier patch (iget_failed) that is to be called to mark an inode as bad, unlock it and release it should the get routine fail. Mark iget() and read_inode() as being obsolete and remove references to them from the documentation. Typically a filesystem will be modified such that the read_inode function becomes an internal iget function, for example the following: void thingyfs_read_inode(struct inode *inode) { ... } would be changed into something like: struct inode *thingyfs_iget(struct super_block *sp, unsigned long ino) { struct inode *inode; int ret; inode = iget_locked(sb, ino); if (!inode) return ERR_PTR(-ENOMEM); if (!(inode->i_state & I_NEW)) return inode; ... unlock_new_inode(inode); return inode; error: iget_failed(inode); return ERR_PTR(ret); } and then thingyfs_iget() would be called rather than iget(), for example: ret = -EINVAL; inode = iget(sb, ino); if (!inode || is_bad_inode(inode)) goto error; becomes: inode = thingyfs_iget(sb, ino); if (IS_ERR(inode)) { ret = PTR_ERR(inode); goto error; } Note that is_bad_inode() does not need to be called. The error returned by thingyfs_iget() should render it unnecessary.
