Subject: [PATCH] rpcrdma: Always release the rpcrdma_device's xa_array
Date: Wed, 30 Oct 2024 16:11:30 -0400	[thread overview]
Message-ID: <20241030201130.47742-1-cel@kernel.org> (raw)

From: Chuck Lever <chuck.lever@oracle.com>

Dai pointed out that the xa_init_flags() in rpcrdma_add_one() needs
to have a matching xa_destroy() in rpcrdma_remove_one() to release
underlying memory that the xarray might have accrued during
operation.

Reported-by: Dai Ngo <dai.ngo@oracle.com>
Fixes: 7e86845a0346 ("rpcrdma: Implement generic device removal")
