[PATCH 5.10 221/226] RDMA/uverbs: Fix typo of sizeof argument

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

 



5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Konstantin Meskhidze <konstantin.meskhidze@xxxxxxxxxx>

commit c489800e0d48097fc6afebd862c6afa039110a36 upstream.

Since size of 'hdr' pointer and '*hdr' structure is equal on 64-bit
machines issue probably didn't cause any wrong behavior. But anyway,
fixing of typo is required.
