[PATCH net] selftests: net: fix rps_default_mask with >32 CPUs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If there is more than 32 cpus the bitmask will start to contain
commas, leading to:

./rps_default_mask.sh: line 36: [: 00000000,00000000: integer expression expected

Remove the commas, bash doesn't interpret leading zeroes as oct
so that should be good enough.

Fixes: c12e0d5f267d ("self-tests: introduce self-tests for RPS default mask")
