Disable sysctl_check.c for embedded targets. This saves about about 11 kB in .text and another 11 kB in .data on a PXA255 embedded platform. Signed-off-by:

This set of patches fixes an proc ->open'less usage due to ->proc_fops flip in the most part of the kernel code. The original OOPS is described in the commit 2d3a4e36: Typical PDE creation code looks like: pde = create_proc_entry("foo", 0, NULL); if (pde) pde->proc_fops = &foo_proc_fops; Notice that PDE is first created, only then ->proc_fops is set up to final value. This is a problem because right after creation a) PDE is fully visible in /proc , and b) ->proc_fops are proc_file_operations which do not have ->open callback. So, it's possible to ->read without ->open (see one class of oopses below). The fix is new API called proc_create() which makes sure ->proc_fops are set up before gluing PDE to main tree. Typical new code looks like: pde = proc_create("foo", 0, NULL, &foo_proc_fops); if (!pde) return -ENOMEM; Fix most networking users for a start. In the long run, create_proc_entry() for regular files will go. In addition to this, proc_create_data is introduced to fix reading from proc without PDE->data. The race is basically the same as above. create_proc_entries is replaced in the entire kernel code as new method is also simply better. This patch: The problem is the same as for de->proc_fops. Right now PDE becomes visible without data set. So, the entry could be looked up without data. This, in most cases, will simply OOPS. proc_create_data call is created to address this issue. proc_create now becomes a wrapper around it. Signed-off-by:

Note: THIS_MODULE and header addition aren't technically needed because this code is not modular, but let's keep it anyway because people can copy this code into modular code. Signed-off-by:Alexey Dobriyan <adobriyan@gmail.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by:

Now that last dozen or so users of ->get_info were removed, ditch it too. Everyone sane shouldd have switched to seq_file interface long ago. P.S.: Co-existing 3 interfaces (->get_info/->read_proc/->proc_fops) for proc is long-standing crap, BTW, thus a) put ->read_proc/->write_proc/read_proc_entry() users on death row, b) new such users should be rejected, c) everyone is encouraged to convert his favourite ->read_proc user or I'll do it, lazy bastards.

Note 1: 0644 should be used, but root bypasses permissions, so writing to /proc/scsi/device_info still works. Note 2: looks like scsi_dev_info_list is unprotected Note 3: probably make proc whine about "unwriteable but with ->write hook" entries. Probably. Signed-off-by:

Probably interface misuse, because of the way iterating over hashbin is done. However! Printing of socket number ("IrNET socket %d - ", i++") made conversion to proper ->start/->next difficult enough to do blindly without hardware. Said that, please apply.
