Date: Fri, 30 Jan 2026 16:42:06 +0100 Message-ID: <20260130154206.1368034-2-lukas@herbolt.com> X-Mailer: git-send-email 2.52.0 Precedence: bulk X-Mailing-List: linux-xfs@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Hi, It was discussed in previous thread [1]. Some older kernels (pre v6.12), complained doing allocation over 2xPAGE_SIZE in krealloc when mounting over 512 unique XFS. The warning was removed in v6.12, but Christoph suggested to start using xrarray instead of plain array. So here it is.
