Now /proc/sys is described in many places and much information is
redundant. This patch updates the proc.txt and move the /proc/sys
desciption out to the files in Documentation/sysctls.
Details are:
merge
- 2.1 /proc/sys/fs - File system data
- 2.11 /proc/sys/fs/mqueue - POSIX message queues filesystem
- 2.17 /proc/sys/fs/epoll - Configuration options for the epoll interface
with Documentation/sysctls/fs.txt.
remove
- 2.2 /proc/sys/fs/binfmt_misc - Miscellaneous binary formats
since it's not better then the Documentation/binfmt_misc.txt.
merge
- 2.3 /proc/sys/kernel - general kernel parameters
with Documentation/sysctls/kernel.txt
remove
- 2.5 /proc/sys/dev - Device specific parameters
since it's obsolete the sysfs is used now.
remove
- 2.6 /proc/sys/sunrpc - Remote procedure calls
since it's not better then the Documentation/sysctls/sunrpc.txt
move
- 2.7 /proc/sys/net - Networking stuff
- 2.9 Appletalk
- 2.10 IPX
to newly created Documentation/sysctls/net.txt.
remove
- 2.8 /proc/sys/net/ipv4 - IPV4 settings
since it's not better then the Documentation/networking/ip-sysctl.txt.
add
- Chapter 3 Per-Process Parameters
to descibe /proc/<pid>/xxx parameters.

NR_OPEN (historically set to 1024*1024) actually forbids processes to open
more than 1024*1024 handles.
Unfortunatly some production servers hit the not so 'ridiculously high
value' of 1024*1024 file descriptors per process.
Changing NR_OPEN is not considered safe because of vmalloc space potential
exhaust.
This patch introduces a new sysctl (/proc/sys/fs/nr_open) wich defaults to
1024*1024, so that admins can decide to change this limit if their workload
needs it.

Sergey Vlasov noticed that there is not kernel.suid_dumpable, but
fs.suid_dumpable.
How KERN_SETUID_DUMPABLE ended up in fs_table[]? Hell knows...

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
