2007-09-05[XFS] fix nasty quota hashtable allocation bugEric Sandeen
This git mod: 77e4635ae191774526ed695482a151ac986f3806 converted to a "greedy" allocation interface, but for the quota hashtables it switched from allocating XFS_QM_HASHSIZE (nr of elements) xfs_dqhash_t's to allocating only XFS_QM_HASHSIZE *bytes* - quite a lot smaller! Then when we converted hsize "back" to nr of elements (the division line) hsize went to 0. This was leading to oopses when running any quota tests on the Fedora 8 test kernel, but the problem has been there for almost a year.

2007-07-17mm: clean up and kernelify shrinker registrationRusty Russell
I can never remember what the function to register to receive VM pressure is called. I have to trace down from __alloc_pages() to find it. It's called "set_shrinker()", and it needs Your Help. 1) Don't hide struct shrinker. It contains no magic. 2) Don't allocate "struct shrinker". It's not helpful. 3) Call them "register_shrinker" and "unregister_shrinker". 4) Call the function "shrink" not "shrinker". 5) Reduce the 17 lines of waffly comments to 13, but document it properly.

2007-07-14[XFS] Quota inode has no parent.David Chinner
Avoid using a special "zero inode" as the parent of the quota inode as this can confuse the filestreams code into thinking the quota inode has a parent. We do not want the quota inode to follow filestreams allocation rules, so pass a NULL as the parent inode and detect this condition when doing stream associations.

2007-05-08[XFS] Invalidate quotacheck when mounting without a quota type.Donald Douwsma
When quotas are mounted or remounted without a particular quota type the quota accounting for that type becomes invalid. Previously we were ignoring this leading to accounting errors.

2007-02-10[XFS] Remove unused header files for MAC and CAP checking functionality.Eric Sandeen
xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.

2007-02-10[XFS] Keep stack usage down for 4k stacks by using noinline.David Chinner
gcc-4.1 and more recent aggressively inline static functions which increases XFS stack usage by ~15% in critical paths. Prevent this from occurring by adding noinline to the STATIC definition. Also uninline some functions that are too large to be inlined and were causing problems with CONFIG_FORCED_INLINING=y. Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.

code to prepare for an upcoming mod which will introduce multi-level in-core extent allocations. Although the in-core extent management is using a new code path in this mod, the functionality remains the same. Major changes include: - Introduce 10 new subroutines which re-orgainze the existing code but do NOT change functionality: xfs_iext_get_ext() xfs_iext_insert() xfs_iext_add() xfs_iext_remove() xfs_iext_remove_inline() xfs_iext_remove_direct() xfs_iext_realloc_direct() xfs_iext_direct_to_inline() xfs_iext_inline_to_direct() xfs_iext_destroy() - Remove 2 subroutines (functionality moved to new subroutines above): xfs_iext_realloc() -replaced by xfs_iext_add() and xfs_iext_remove() xfs_bmap_insert_exlist() - replaced by xfs_iext_insert() xfs_bmap_delete_exlist() - replaced by xfs_iext_remove() - Replace all hard-coded (indexed) extent assignments with a call to xfs_iext_get_ext() - Replace all extent record pointer arithmetic (ep++, ep--, base + lastx,..) with calls to xfs_iext_get_ext() - Update comments to remove the idea of a single "extent list" and introduce "extent record" terminology instead SGI-PV: 928864 SGI-Modid: xfs-linux-melb:xfs-kern:207390a Signed-off-by: Mandy Kirkconnell <alkirkco@sgi.com> Signed-off-by: Nathan Scott <nathans@sgi.com>

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
