[Crash-utility] [PATCH v2 0/1] Filter ps output by scheduling policy

In CEE we often analyze vmcores from customers and sometimes want to filter tasks by scheduling policy, for instance, to identify if customer runs realtime tasks. Doing this via foreach grepping and then feeding back pointers to task_struct and grepping it again is very slow, especially if customer runs thousands of tasks. So, let's add another option for ps to filter tasks by scheduling policy. Changes in v2: * handle task_struct.policy member size correctly * accept comma-separated list of policies instead of requiring multiple -y arguments * policy can be specified as a number too * policy name is case-insensitive now * warn about incorrect policy name * fix help message formatting * mark upper_case() source string pointer as a const (minor cleanup) Oleksandr Natalenko (1): task: also filter ps output by ->policy defs.h | 15 +++++++- help.c | 7 +++- task.c | 135 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++--- tools.c | 5 ++- 4 files changed, 152 insertions(+), 10 deletions(-) -- 2.14.2
