libfs: allow error return from simple attributes

2008-02-08T17:22:34Z

Sometimes simple attributes might need to return an error, e.g. for acquiring a mutex interruptibly. In fact we have that situation in spufs already which is the original user of the simple attributes. This patch merged the temporarily forked attributes in spufs back into the main ones and allows to return errors.

debugfs: Add debugfs_create_u64()

2007-04-27T17:57:31Z

I went to use this the other day, only to find it didn't exist. It's a straight copy of the debugfs u32 code, then s/u32/u64/. A quick test shows it seems to be working. Signed-off-by: Michael Ellerman Signed-off-by: Greg Kroah-Hartman

debugfs: implement symbolic links

2007-02-16T23:19:17Z

debugfs: implement symbolic links Implement a new function debugfs_create_symlink() which can be used to create symbolic links in debugfs. This function can be useful for people moving functionality from /proc to debugfs (e.g. the gcov-kernel patch). Signed-off-by: Peter Oberparleiter Signed-off-by: Greg Kroah-Hartman

[PATCH] mark struct file_operations const 6

2007-02-12T17:48:45Z

Many struct file_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. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private

2006-09-27T15:26:17Z

The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.
