2006-03-28[PATCH] Make most file operations structs in fs/ constArjan van de Ven
This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-03-26[PATCH] sem2mutex: fs/Ingo Molnar
Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.

2006-03-06[PATCH] cramfs mounts provide corrupted content since 2.6.15Dave Johnson
Fix handling of cramfs images created by util-linux containing empty regular files. Images created by cramfstools 1.x were ok. Fill out inode contents in cramfs_iget5_set() instead of get_cramfs_inode() to prevent issues if cramfs_iget5_test() is called with I_LOCK|I_NEW still set.

2005-09-07[PATCH] fix cramfs making duplicate entries in inode cacheDave Johnson
Every time cramfs_lookup() is called to lookup and inode for a dentry, get_cramfs_inode() will allocate a new inode without checking to see if that inode already exists in the inode cache. This is fine the first time, but if the dentry cache entry(ies) associated with that inode are aged out, but the inode entry is not aged out (which can be quite common if the inode has buffer cache linked to it), cramfs_lookup() will be called again and another inode will be allocated and added to the inode cache creating a duplicate in the inode cache. The big issue here is that the buffers associated with each inode cache entry are not shared between the duplicates! The older inode entries are now orphaned as no dentry points to it and won't be freed until the buffer cache assoicated with them are first freed. The newest entry will have to create all new buffer cache for each part of its file as the old buffer cache is now orphaned as well. Patch below fixes this by making get_cramfs_inode() use the inode cache before blindly creating a new entry every time. This eliminates the duplicate inodes and duplicate buffer cache.

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!
