Regression: False positive I1101(c-extension-no-member) for math.iclose

[sam-s]

Bug description

math.isclose has been around since 3.5, but now I am getting c-extension-no-member for it (I did not see that before).

The same error for ceil, log, sqrt &c

The same for resource.getrusage and zlib.crc32 (and other functions in those modules)

Also, no-member for dbm.gnu.open and socket.AF_INET.

File:

"https://github.com/PyCQA/pylint/issues/5081"
import math
math.isclose(1,2)

Configuration

No response

Command used

pylint a.py

Pylint output

Also I get

[E1101(no-member), ...] Instance of 'finfo' has no 'resolution' member

for np.finfo(np.float64).resolution despite extension-pkg-allow-list=numpy

I'm seeing the same issue myself. I'm using pylint 2.10.2 and Python 3.9.7.
