Hello, all.
This is the third patchset of four sysfs update patchset series[1] and
to be applied on top of the second patchset[2].
Currently, sysfs interface is based on kobj. This made more sense
before because
Currently name is implicitly copied for directory and symlink nodes.
Make the behavior flexible by making it a flag. If SYSFS_COPY_NAME
bit is specified in @mode when calling sysfs_new_dirent(), the name is
copied.
SYSFS_COPY_NAME is defined as S_IFMT so that it can be specified with
@mode bits.
In the upcoming new sysfs interface, sysfs_root will be exported. To
ease usage and make dummy declaration easier, make sysfs_root a
pointer.

Rename sysfs_rename_mutex to sysfs_op_mutex and protect operations
which modify tree with it. ie.
sysfs_op_mutex : above i_mutexes in the lock hierarchy and
guarantees exclusion against all tree
modifications.
sysfs_mutex: under i_mutexes in the
sysfs_assoc_lock which protects kobj - sd association is now only
used in fs/sysfs/kobject.c. Move it there and make it static.

sysfs_add_file() creates a text sysfs file which is equivalent to
attribute file of the original API. Each sysfs file has its own ops
containing show and store, and can have arbitrary private data. Both
show and store methods are given two private data arguments - one for
its own, the other for
sysfs_add_bin() creates a binary sysfs file which is equivalent to
binary attribute file of the original API. As with file, bin ops take
private data of both itself and parent to support kobject based API
and kobject based interface works by setting parent_data to kobj and
data to battr.

NAK. keepinitrd is what people expect on ARM.
I'm frustrated that whoever invented retain_initrd didn't look
around in the documentation to see if there was any existing
implementation first. The generic implementation should be fixed
IMHO, or at least the option string moved into

Well, the patch could be less, but there's still the possibility of a kernel
service wanting to override the capabilities mask.

Sorry, I don't understand you. What are 0= directories?
When building a kernel you can specify an other output directory
so you do not mix up your source tree with generated files.

When a sysfs_node is removed, automatically remove all symlinks
pointing to it together.
Note that as links created with kobject based sysfs_create_link()
aren't chained on its target, they aren't removed automatically. This
is for backward compatibility.

Hello, all.
This is the fourth patchset of four sysfs update patchset series[1]
and to be applied on top of the third patchset[2].
This patchset implements the following new features.
* Notify pollers on file deactivation.
* Name-formatting for symlinks. e.g. symlink pointing to
Notify file on deactivation so that the pollers get event when the
polled file dies, which is very easy to implement with sd based
interface.

This patch implements sysfs name formatting. sysfs_add_link() is
passed @name_fmt instead of @fmt. In the format string only
%[:alnum:] and %% are handled specially. %0 is substitued with
the name of @target, %3 with the name of the third ancestor of
@target, %[aA] the 10th and %[zZ] with 35th.
Add sd-s_dir.links and sd-s_link.next and chain symlinks to their
targets. This will be used to implement auto-removal and auto-rename
of symlinks.
Symlinks created with kobject-based sysfs_create_symlink() won't be
chained to keep backward compatibility.
