2011-07-20fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik
Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

2011-05-09HPFS: Introduce a global mutex and lock it on every callback from VFS.Mikulas Patocka
Introduce a global mutex and lock it on every callback from VFS. Performance doesn't matter, reviewing the whole code for locking correctness would be too complicated, so simply lock it all.

2011-03-02hpfs: remove the BKLArnd Bergmann
This removes the BKL in hpfs in a rather awful way, by making the code only work on uniprocessor systems without kernel preemption, as suggested by Andi Kleen. The HPFS code probably has close to zero remaining users on current kernels, all archeological uses of the file system can probably be done with the significant restrictions. The hpfs_lock/hpfs_unlock functions are left in the code, sincen Mikulas has indicated that he is still interested in fixing it in a better way.

2007-02-12[PATCH] mark struct inode_operations const 2Arjan van de Ven
Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

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>

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!
