driver core: Suppress sysfs warnings for device_rename().

Renaming network devices to an already existing name is not
something we want sysfs to print a scary warning for, since the
callers can deal with this correctly. So let's introduce
sysfs_create_link_nowarn() which gets rid of the common warning.

sysfs: build fix

2008-05-05T00:07:03+00:00

x86.git testing found the following build failure on v2.6.26-rc1:

  In file included from include/linux/kobject.h:22,
                   from include/linux/module.h:17,
                   from include/linux/crypto.h:22,
                   from arch/x86/kernel/asm-offsets_32.c:8,
                   from arch/x86/kernel/asm-offsets.c:3:
  include/linux/sysfs.h:201: error: redefinition of 'sysfs_update_group'
  include/linux/sysfs.h:195: error: previous definition of 'sysfs_update_group' was here
  make[1]: *** [arch/x86/kernel/asm-offsets.s] Error 1
  make: *** [prepare0] Error 2

with the following config:

    http://redhat.com/~mingo/misc/config-Sun_May__4_07_09_30_CEST_2008.bad

the reason for the build failure is the duplicate definition of the
sysfs_update_group() inline function in include/linux/sysfs.h.

The duplication was a merge error: it was added via -mm by commit
v2.6.25-7262-g2850699, "sysfs: sysfs_update_group stub for
CONFIG_SYSFS=n" a day before v2.6.26-rc1, but a day before that the same
commit was already merged upstream via the sysfs tree, with commit
v2.6.25-7211-g1cbfb7a.

sysfs: sysfs_update_group stub for CONFIG_SYSFS=n

2008-05-01T15:03:59+00:00

scsi_transport_spi uses sysfs_update_group() when CONFIG_SYSFS=n, so provide a
stub for it.

[SCSI] sysfs: make group is_valid return a mode_t

2008-04-22T20:16:31+00:00

We have a problem in scsi_transport_spi in that we need to customise
not only the visibility of the attributes, but also their mode.  Fix
this by making the is_visible() callback return a mode, with 0
indicating is not visible.

Also add a sysfs_update_group() API to allow us to change either the
visibility or mode of the files at any time on the fly.

sysfs: small header file cleanup for SYSFS=n

2008-04-20T02:10:20+00:00

Convert sysfs_remove_bin_file() to have a return type of 'void' for
!CONFIG_SYSFS configurations.  Also removes unnecessary colons from empty
void functions.

[SCSI] sysfs: add filter function to groups

2008-01-23T17:29:18+00:00

This patch allows the various users of attribute_groups to selectively
allow the appearance of group attributes.  The primary consumer of
this will be the transport classes in which we currently have
elaborate attribute selection algorithms to do this same thing.

sysfs: add copyrights

sysfs: kill sysfs_update_file()

2007-10-12T21:51:09+00:00

sysfs_update_file() depends on inode->i_mtime but sysfs iondes are now
reclaimable making the reported modification time unreliable.  There's
only one user (pci hotplug) of this notification mechanism and it
reportedly isn't utilized from userland.

Kill sysfs_update_file().

sysfs: clean up header files

2007-10-12T21:51:09+00:00

sysfs is about to go through major overhaul making this a pretty good
opportunity to clean up (out-of-tree changes and pending patches will
need regeneration anyway).  Clean up headers.

* Kill space between * and symbolname.

* Move SYSFS_* type constants and flags into fs/sysfs/sysfs.h.
  They're internal to sysfs.

* Reformat function prototypes and add argument symbol names.

* Make dummy function definition order match that of function
  prototypes.

* Add some comments.

* Reorganize fs/sysfs/sysfs.h according to which file the declared
  variable or feature lives in.

This patch does not introduce any behavior change.
