rcu: Make SRCU optional by using CONFIG_SRCU 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. text data bss dec hex filename 2007 0 0 2007 7d7 kernel/rcu/srcu.o Size of arch/powerpc/boot/zImage changes from text data bss dec hex filename 831552 64180 23944 919676 e087c arch/powerpc/boot/zImage : before 829504 64180 23952 917636 e0084 arch/powerpc/boot/zImage : after so the savings are about ~2000 bytes.

Note that gfs2 and xfs use their own quota system.
Ext3, ext4 and reiserfs also support journaled quotas for which
you don't need to run quotacheck(8) after an unclean shutdown.

VFS: Export dquot_send_warning 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.

If you say Y here, quota warnings (about exceeding softlimit, reaching

Note that this behavior is currently deprecated and may go away in
future. Please use notification via netlink socket instead.
quota: Convert __DQUOT_PARANOIA symbol to standard config option 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. Signed-off-by: Jan Kara <jack@suse.cz>
