# # Quota configuration # config QUOTA bool "Quota support" select QUOTACTL select SRCU help If you say Y here, you will be able to set per user limits for disk usage (also called disk quotas). Currently, it works for the ext2, ext3, ext4, jfs, ocfs2 and reiserfs file systems. 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. For further details, read the Quota mini-HOWTO, available from , or the documentation provided with the quota tools. Probably the quota support is only useful for multi user systems.

x86/mce: Make timer handling more robust
Erik reported that on a preproduction hardware a CMCI storm triggers the BUG_ON in add_timer_on(). The reason is that the per CPU MCE timer is started by the CMCI logic before the MCE CPU hotplug callback starts the timer with add_timer_on(). So the timer is already queued which triggers the BUG. Using add_timer_on() is pretty pointless in this code because the timer is strictlty per CPU, initialized as pinned and all operations which arm the timer happen on the CPU to which the timer belongs. Simplify the whole machinery by using mod_timer() instead of add_timer_on() which avoids the problem because mod_timer() can handle already queued timers. Use __start_timer() everywhere so the earliest armed expiry time is preserved.
