Subject: [PATCH v3 0/2] chardev/char-mux: tweak mux bitset operations
Date: Fri, 29 Nov 2024 11:32:37 +0100 [thread overview]
Message-ID: <20241129103239.464061-1-r.peniaev@gmail.com> (raw)
Patchset tweaks bitset operations by changing a constant to unsigned
long, introduces a static compile check and simplifies bitset operations.
Also resolves Coverity CID 1563776.
v2..v3:
* Multiply (sizeof(d->mux_bitset) * BITS_PER_BYTE) to get number
of bits (thanks Paolo Bonzini for noticing that)
* Rebase on latest master
v1..v2:
* Rebase on latest master, incorporate review tags.
Roman Penyaev (2):
chardev/char-mux: shift unsigned long to avoid 32-bit overflow
chardev/char-mux: make boolean bit check instead of find_next_bit()
