perf tools: Fix build error on generated/fs_at_flags_array.c

2024-12-04T22:34:50Z

It should only have generic flags in the array but the recent header sync brought a new flags to fcntl.h and caused a build error. Let's update the shell script to exclude flags specific to name_to_handle_at().

perf beauty: Update copy of linux/socket.h with the kernel sources

2024-09-30T20:23:38Z

To pick the changes in: 8f0b3cc9a4c102c2 ("tcp: RX path for devmem TCP") That don't result in any changes in the tables generated from that header. But while updating I noticed we need to support the new MSG_SOCK_DEVMEM flag in the hard coded table for the msg flags table, add it.

We need to improve this situation, as not all AT_ defines are applicable to all fs flags...

Picking the changes from: 37745918e0e7575b ("ALSA: timer: Introduce virtual userspace-driven timers") Which entails no changes in the tooling side as it only introduces new SNDRV_TIMER_IOCTL_ ioctls, and the ones tracked by scripts in tools/perf/trace/beauty/ are only SNDRV_PCM_IOCTL_ and SNDRV_CTL_IOCTL_, we still need to support SNDRV_TIMER_IOCTL_ ones, but that probably will be one of the first for a BTF enumeration based approach :-) This silences this perf tools build warning: diff -u tools/perf/trace/beauty/include/uapi/sound/asound.h include/uapi/sound/asound.h Cc: Adrian Hunter Cc: Ian Rogers Cc: Ivan Orlov Cc: Jiri Olsa Cc: Kan Liang Cc: Namhyung Kim Cc: Takashi Iwai Link: https://lore.kernel.org/lkml/ZvrB-g_E7g2ArlYW@x1 Signed-off-by: Arnaldo Carvalho de Melo
