[PATCH 0/9] treewide: eliminate anonymous module_init & module_exit

[PATCH 0/9] treewide: eliminate anonymous module_init & module_exit

[Randy Dunlap]

There are a number of drivers that use "module_init(init)" and
"module_exit(exit)", which are anonymous names and can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init
 ffffffff832fca05 t init
 ffffffff832fcbd2 t init
 ffffffff83328f0e t init
 ffffffff8332c5b1 t init
 ffffffff8332d9eb t init
 ffffffff8332f0aa t init
 ffffffff83330e25 t init
 ffffffff833317a5 t init
 ffffffff8333dd6b t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs
 calling  init+0x0/0x73 @ 1
 initcall init+0x0/0x73 returned 0 after 6 usecs
 calling  init+0x0/0x73 @ 1
 initcall init+0x0/0x73 returned 0 after 4 usecs
 calling  init+0x0/0xf5 @ 1
 initcall init+0x0/0xf5 returned 0 after 27 usecs
 calling  init+0x0/0x7d @ 1
 initcall init+0x0/0x7d returned 0 after 11 usecs
 calling  init+0x0/0xc9 @ 1
 initcall init+0x0/0xc9 returned 0 after 19 usecs
 calling  init+0x0/0x9d @ 1
 initcall init+0x0/0x9d returned 0 after 37 usecs
 calling  init+0x0/0x63f @ 1
 initcall init+0x0/0x63f returned 0 after 411 usecs
 calling  init+0x0/0x171 @ 1
 initcall init+0x0/0x171 returned 0 after 61 usecs
 calling  init+0x0/0xef @ 1
 initcall init+0x0/0xef returned 0 after 3 usecs

[PATCH 1/9] virtio_blk: eliminate anonymous module_init & module_exit

[Randy Dunlap]

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

If this is done tree-wide, it's ok to do it for virtio too.

No real opinion on whether it's a good idea.

[PATCH 2/9] virtio_console: eliminate anonymous module_init & module_exit

[Randy Dunlap]

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

I don't think the Fixes-by really applies here, though - we don't
really want to push this into stable, nor do we want any automated
tools to pick this up because of that tag..

If this is done tree-wide, it's ok to do it for virtio too.

[PATCH 3/9] net: mlx5: eliminate anonymous module_init & module_exit

[Randy Dunlap]

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)

 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

If this is done tree-wide, it's ok to do it for virtio too.

Acked-by: Michael S. Tsirkin <mst@redhat.com>

No real opinion on whether it's a good idea.

[PATCH 6/9] usb: gadget: eliminate anonymous module_init & module_exit

[Randy Dunlap]

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

I continue to be confused about the latest rules for the Fixes tag but this one
in particular seems completely useless.  This is the 'beginning of time' commit
by Linus AFAICT.  So do any of these Fixes tags need to be in this series?

Regardless:

I guess it mostly depends on whether they get applied to stable trees, but
it's entirely fine with me if they don't.

[PATCH 7/9] usb: usbip: eliminate anonymous module_init & module_exit

[Randy Dunlap]

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

[PATCH 9/9] testmmiotrace: eliminate anonymous module_init & module_exit

[Randy Dunlap]

Eliminate anonymous module_init() and module_exit(), which can lead to
confusion or ambiguity when reading System.map, crashes/oops/bugs,
or an initcall_debug log.

Give each of these init and exit functions unique driver-specific
names to eliminate the anonymous names.

Example 1: (System.map)
 ffffffff832fc78c t init
 ffffffff832fc79e t init
 ffffffff832fc8f8 t init

Example 2: (initcall_debug log)
 calling  init+0x0/0x12 @ 1
 initcall init+0x0/0x12 returned 0 after 15 usecs
 calling  init+0x0/0x60 @ 1
 initcall init+0x0/0x60 returned 0 after 2 usecs
 calling  init+0x0/0x9a @ 1
 initcall init+0x0/0x9a returned 0 after 74 usecs

I'm not fully sure about the Fixes tags but I don't see that it hurts anything.
