* | [PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | As Pekka Enberg pointed out, with the if still following the else, you can still get a null uid written to the disk if you specify a default uid= without uid=forget. In other words, if the desktop user is uid=1000 and the mount option uid=1000 is given ( which is done on ubuntu automatically and probably other distributions that use hal ), then if any other user besides uid 1000 owns a file then a 0 will be written to the media as the owning uid instead.

* | [PATCH] 9p: fix name consistency problemsEric Van Hensbergen2006-03-25
|/ | | | | | | | | | | | | | | | There were a number of conflicting naming schemes used in the v9fs project. The directory was fs/9p, but MAINTAINERS and Documentation referred to v9fs. The module name itself was 9p2000, and the file system type was 9P. This patch attempts to clean that up, changing all references to 9p in order to match the directory name. We'll also start using 9p instead of v9fs as our patch prefix. There is also a minor consistency cleanup in the options changing the name option to uname in order to more closely match the Plan 9 options.

* [PATCH] tmpfs: fix mount mpol nodelist parsingHugh Dickins2006-02-21
| | | | | | | | | | | | | | | | | | | | | | | I've been dissatisfied with the mpol_nodelist mount option which was added to tmpfs earlier in -rc. Replace it by mpol=policy:nodelist. And it was broken: a nodelist is a comma-separated list of numbers and ranges; the mount options are a comma-separated list of token=values. Whoops, blindly strsep'ing on commas doesn't work so well: since we've no numeric tokens, and unlikely to add them, use that to distinguish. Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject all its options as invalid if not NUMA. /proc shows MPOL_PREFERRED as "prefer", so use that name for the policy instead of "preferred". Enforce that mpol=default has no nodelist; that mpol=prefer has one node only; that mpol=bind has a nodelist; but let mpol=interleave use node_online_map if no nodelist given.

* [PATCH] Add tmpfs options for memory placement policiesRobin Holt2006-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Anything that writes into a tmpfs filesystem is liable to disproportionately decrease the available memory on a particular node. Since there's no telling what sort of application (e.g. dd/cp/cat) might be dropping large files there, this lets the admin choose the appropriate default behavior for their site's situation. Introduce a tmpfs mount option which allows specifying a memory policy and a second option to specify the nodelist for that policy. With the default policy, tmpfs will behave as it does today. This patch adds support for preferred, bind, and interleave policies. The default policy will cause pages to be added to tmpfs files on the node which is doing the writing. Some jobs expect a single process to create and manage the tmpfs files. This results in a node which has a significantly reduced number of free pages. With this patch, the administrator can specify the policy and nodes for that policy where they would prefer allocations. This patch was originally written by Brent Casavant and Hugh Dickins. I added support for the bind and preferred policies and the mpol_nodelist mount option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the current version of the spu file system, used for driving SPEs on the Cell Broadband Engine. This release is almost identical to the version for the 2.6.14 kernel posted earlier, which is available as part of the Cell BE Linux distribution from http://www.bsc.es/projects/deepcomputing/linuxoncell/. The first patch provides all the interfaces for running spu application, but does not have any support for debugging SPU tasks or for scheduling. Both these functionalities are added in the subsequent patches. See Documentation/filesystems/spufs.txt on how to use spufs.

* | [PATCH] drop-pagecacheAndrew Morton2006-01-08
|/ | | | | | | | | | | | | | | | | | | | | | Add /proc/sys/vm/drop_caches. When written to, this will cause the kernel to discard as much pagecache and/or reclaimable slab objects as it can. THis operation requires root permissions. It won't drop dirty data, so the user should run `sync' first. Caveats: a) Holds inode_lock for exorbitant amounts of time. b) Needs to be taught about NUMA nodes: propagate these all the way through so the discarding can be controlled on a per-node basis. This is a debugging feature: useful for getting consistent results between filesystem benchmarks. We could possibly put it under a config option, but it's less than 300 bytes.
