* fs/proc: don't use module_init for non-modular core codePaul Gortmaker2014-01-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | PROC_FS is a bool, so this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be ugly at best. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of fs_initcall (which makes sense for fs code) will thus change these registrations from level 6-device to level 5-fs (i.e. slightly earlier). However no observable impact of that small difference has been observed during testing, or is expected. Also note that this change uncovers a missing semicolon bug in the registration of vmcore_init as an initcall.

* procfs: fix /proc/softirqs formattingDavidlohr Bueso2010-10-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The length of the BLOCK_IPOLL string is making i's value be printed too far to the right. This patch fixes this and makes the output a bit neater.

* proc: export statistics for softirq to /procKeika Kobayashi2009-06-181-0/+44
Export statistics for softirq in /proc/softirqs and /proc/stat. 1. /proc/softirqs Implement /proc/softirqs which shows the number of softirq for each CPU like /proc/interrupts. 2. /proc/stat Add the "softirq" line to /proc/stat. This line shows the number of softirq for all cpu. The first column is the total of all softirqs and each subsequent column is the total for particular softirq.
