PRINT_QUOTA_WARNING is deprecated since commit 8e8934695dfd ("quota:
send messages via netlink") merged in 2007. Users should rather be using
notification over netlink socket if they are interested about explicit
notification in addition to plain EDQUOT error. Since printing to
console from deep inside filesystem code is problematic, mark the
feature as BROKEN now and see who complains.

Now that the SRCU Kconfig option is unconditionally selected, there is
no longer any point in selecting it. Therefore, remove the "select SRCU"
Kconfig statements.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

SRCU is not necessary to be compiled by default in all cases. For tinification
efforts not compiling SRCU unless necessary is desirable.
The current patch tries to make compiling SRCU optional by introducing a new
Kconfig option CONFIG_SRCU which is selected when any of the components making
use of SRCU are selected.
If we do not select CONFIG_SRCU, srcu.o will not be compiled at all.

Remove "depends on" line from QUOTACTL config option and rather select
the option explicitely from config options which need it. It makes more
sense this way and also fixes Kconfig warning due to GFS2 selecting
QUOTACTL but QUOTACTL not depending on it.

Make __DQUOT_PARANOIA define from the old days a standard config option
and turn it off by default.
This gets rid of a quota warning about writes before quota is turned on
for systems with ext4 root filesystem. Currently there's no way to legally
solve this because /etc/mtab has to be written before quota is turned on
on most systems.

So far the maximum quota space limit was 4TB. Apparently this isn't enough
for Lustre guys anymore. So implement new quota format which raises block
limits to 2^64 bytes. Also store number of inodes and inode limits in
64-bit variables as 2^32 files isn't that insanely high anymore.
The first version of the patch has been developed by Andrew Perepechko
<Andrew.Perepechko@Sun.COM>.

Sending a message to userspace in a generic format to warn
of events (e.g. quota exceeded) in the quota subsystem is
a generically useful feature. This patch makes some minor
changes to the send_message function from dquot.c renaming
it quota_send_message, moving it to quota.c and exporting it
for use by filesystems which do not use the dquot code.
