It should be in a proper mnt namespace when accessing the file.
I think this had no problem since the build-id was actually read from

Hello,
This is the new version of speed up build-id injection. As this is

No need to load symbols in a DSO when injecting build-id. I guess the

Like perf record, we can even more speedup build-id processing by just

As stated in platform/44x/Kconfig, CONFIG_PPC_47x is not
compatible with 440 and 460 variants.
This is confirmed in asm/cache.h as L1_CACHE_SHIFT is different
for 47x, meaning a kernel built for 47x will not run correctly
on a 440.
In cputable, opt out all 440 and 460 variants when CONFIG_PPC_47x
440/460 variants and 470 variants are not compatible, no
need to make code supporting both and using MMU features.
Just use CONFIG_PPC_47x to decide what to build.

When there is no clients listening on event the trace return
EBADF. The file is not a bad file descriptor and to get the
userspace able to do a proper error handling it need a different
error code that separate a bad file descriptor from a empty listening.

Hi Ulf,
Regarding this patch, we also want to fix the EMI of one hardware
using the old version(such as v5.4).
Is there a chance to append a Fixes tag on this patch ?
Or what should I do ?
