seq_file: constify seq_operations

2009-09-23T14:39:29Z

Make all seq_operations structs const, to help mitigate against revectoring user-triggerable function pointers. This is derived from the grsecurity patch, although generated from scratch because it's simpler than extracting the changes from there.

lockdep: Remove recursion stattistics

2009-08-29T11:22:36Z

Since lockdep has introduced BFS to avoid recursion, statistics for recursion does not make any sense now. So remove them. Signed-off-by: Ming Lei Cc: a.p.zijlstra@chello.nl LKML-Reference: <1251542879-5211-1-git-send-email-tom.leiming@gmail.com> Signed-off-by: Ingo Molnar

lockdep: Simplify lock_stat seqfile code

2009-08-17T07:54:41Z

- make ls_next() call ls_start() - remove redundant code in lock_stat_release() Signed-off-by: Li Zefan Cc: Peter Zijlstra LKML-Reference: <4A88ED6B.6030602@cn.fujitsu.com> Signed-off-by: Ingo Molnar

lockdep: Simplify lockdep_chains seqfile code

2009-08-17T07:54:41Z

- make lc_next() call lc_start() - use lock_chains directly instead of storing it in m->private Signed-off-by: Li Zefan Cc: Peter Zijlstra LKML-Reference: <4A88ED57.5060609@cn.fujitsu.com> Signed-off-by: Ingo Molnar

lockdep: Fix missing entries in /proc/lock_chains

2009-08-17T07:54:40Z

Two entries are missing in the output of /proc/lock_chains. One is chains[1]. When lc_next() is called the 1st time, chains[0] is returned. And when it's called the 2nd time, chains[2] is returned. The other missing ons is, when lc_start() is called the 2nd time, we should start from chains[@pos-1] but not chains[@pos], because pos == 0 is the header.

lockdep: Fix missing entry in /proc/lock_stat

2009-08-17T07:54:39Z

One entry is missing in the output of /proc/lock_stat. The cause is, when ls_start() is called the 2nd time, we should start from stats[@pos-1] but not stats[@pos], because pos == 0 is the header.

lockdep: Fix BFS build

2009-08-02T12:51:06Z

Fix: kernel/built-in.o: In function `lockdep_stats_show': lockdep_proc.c:(.text+0x48202): undefined reference to `max_bfs_queue_depth' As max_bfs_queue_depth is only available under CONFIG_PROVE_LOCKING=y. Cc: Ming Lei Cc: Peter Zijlstra LKML-Reference: Signed-off-by: Ingo Molnar
