2006-06-21[PATCH] Driver core: add generic "subsystem" link to all devicesKay Sievers
Like the SUBSYTEM= key we find in the environment of the uevent, this creates a generic "subsystem" link in sysfs for every device. Userspace usually doesn't care at all if its a "class" or a "bus" device. This provides an unified way to determine the subsytem of a device, regardless of the way the driver core has created it.

2006-06-20[PATCH] inotify (1/5): split kernel API from userspace supportAmy Griffis
The following series of patches introduces a kernel API for inotify, making it possible for kernel modules to benefit from inotify's mechanism for watching inodes. With these patches, inotify will maintain for each caller a list of watches (via an embedded struct inotify_watch), where each inotify_watch is associated with a corresponding struct inode. The caller registers an event handler and specifies for which filesystem events their event handler should be called per inotify_watch.

2006-06-03[JFFS2] Remove stray __exit from jffs2_compressors_exit()David Woodhouse
It's used from the initfunc in case of failure too. We could actually do with an '__initexit' for this kind of thing -- when built in to the kernel, it could do with being dropped with the init text. We _could_ actually just use __init for it, but that would break if/when we start dropping init text from modules. So let's just leave it as it was for now, and mutter a little more about random 'janitorial' fixes from people who aren't paying attention to what they're doing.

2006-05-29[MTD] Rework the out of band handling completelyThomas Gleixner
Hopefully the last iteration on this! The handling of out of band data on NAND was accompanied by tons of fruitless discussions and halfarsed patches to make it work for a particular problem. Sufficiently annoyed by I all those "I know it better" mails and the resonable amount of discarded "it solves my problem" patches, I finally decided to go for the big rework. After removing the _ecc variants of mtd read/write functions the solution to satisfy the various requirements was to refactor the read/write _oob functions in mtd. The major change is that read/write_oob now takes a pointer to an operation descriptor structure "struct mtd_oob_ops".instead of having a function with at least seven arguments. read/write_oob which should probably renamed to a more descriptive name, can do the following tasks: - read/write out of band data - read/write data content and out of band data - read/write raw data content and out of band data (ecc disabled) struct mtd_oob_ops has a mode field, which determines the oob handling mode. Aside of the MTD_OOB_RAW mode, which is intended to be especially for diagnostic purposes and some internal functions e.g. bad block table creation, the other two modes are for mtd clients: MTD_OOB_PLACE puts/gets the given oob data exactly to/from the place which is described by the ooboffs and ooblen fields of the mtd_oob_ops strcuture. It's up to the caller to make sure that the byte positions are not used by the ECC placement algorithms. MTD_OOB_AUTO puts/gets the given oob data automaticaly to/from the places in the out of band area which are described by the oobfree tuples in the ecclayout data structre which is associated to the devicee. The decision whether data plus oob or oob only handling is done depends on the setting of the datbuf member of the data structure. When datbuf == NULL then the internal read/write_oob functions are selected, otherwise the read/write data routines are invoked. Tested on a few platforms with all variants. Please be aware of possible regressions for your particular device / application scenario Disclaimer: Any whining will be ignored from those who just contributed "hot air blurb" and never sat down to tackle the underlying problem of the mess in the NAND driver grown over time and the big chunk of work to fix up the existing users. The problem was not the holiness of the existing MTD interfaces. The problems was the lack of time to go for the big overhaul. It's easy to add more mess to the existing one, but it takes alot of effort to go for a real solution. Improvements and bugfixes are welcome! Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2006-05-24JFS: Fix multiple errors in metapage_releasepageDave Kleikamp
It looks like metapage_releasepage was making in invalid assumption that the releasepage method would not be called on a dirty page. Instead of issuing a warning and releasing the metapage, it should return 0, indicating that the private data for the page cannot be released. I also realized that metapage_releasepage had the return code all wrong. If it is successful in releasing the private data, it should return 1, otherwise it needs to return 0. Lastly, there is no need to call wait_on_page_writeback, since try_to_release_page will not call us with a page in writback state. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
