remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59Z

We need to work on cleaning up the relationship between kobjects, ksets and ktypes. The removal of 'struct subsystem' is the first step of this, especially as it is not really needed at all. Thanks to Kay for fixing the bugs in this patch. Signed-off-by: Greg Kroah-Hartman

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: Remove misleading comments.

2007-02-16T23:19:17Z

Just mention which error will be returned if debugfs is disabled. Callers should be able to figure out themselves what they need to check. Signed-off-by: Cornelia Huck 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

DebugFS : file/directory removal fix

2006-12-13T23:38:45Z

Fix file and directory removal in debugfs. Add inotify support for file removal. The following scenario : create dir a create dir a/b cd a/b (some process goes in cwd a/b) rmdir a/b rmdir a fails due to the fact that "a" appears to be non empty. It is because the "b" dentry is not deleted from "a" and still in use. The same problem happens if "b" is a file. d_delete is nice enough to know when it needs to unhash and free the dentry if nothing else is using it or, if someone is using it, to remove it from the hash queues and wait for it to be deleted when it has no users. The nice side-effect of this fix is that it calls the file removal notification. Signed-off-by: Mathieu Desnoyers Signed-off-by: Greg Kroah-Hartman

DebugFS : more file/directory creation error handling

2006-12-13T23:38:45Z

Correct dentry count to handle creation errors. This patch puts a dput at the file creation instead of the file removal : lookup_one_len already returns a dentry with reference count of 1. Then, the dget() in simple_mknod increments it when the dentry is associated with a file. In a scenario where simple_create or simple_mkdir returns an error, this would lead to an unwanted increment of the reference counter, therefore making file removal impossible.

DebugFS : file/directory creation error handling

2006-12-13T23:38:45Z

Fix error handling of file and directory creation in DebugFS. The error path should release the file system because no _remove will be called for this erroneous creation. Signed-off-by: Mathieu Desnoyers Signed-off-by: Greg Kroah-Hartman

DebugFS : coding style fixes

2006-12-13T23:38:45Z

Minor coding style fixes along the way : 80 cols and a white space. Signed-off-by: Mathieu Desnoyers Signed-off-by: Greg Kroah-Hartman

DebugFS : inotify create/mkdir support
