+Subject: io_uring: mem-account pbuf buckets
+
+From: Pavel Begunkov <asml.silence@gmail.com>
+
+commit cc18cc5e82033d406f54144ad6f8092206004684 upstream.
+
+Potentially, someone may create as many pbuf bucket as there are indexes
+in an xarray without any other restrictions bounding our memory usage,
+put memory needed for the buckets under memory accounting.

+Subject: Revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP"
+
+From: Jose Alonso <joalonsof@gmail.com>
+
+commit 6fd2c17fb6e02a8c0ab51df1cfec82ce96b8e83d upstream.
+
+This reverts commit 36a15e1cb134c0395261ba1940762703f778438c.
+
+The usage of FLAG_SEND_ZLP causes problems to other firmware/hardware
+versions that have no issues.
+
+The FLAG_SEND_ZLP is not safe to use in this context.
+See:
+https://patchwork.ozlabs.org/project/netdev/patch/1270599787.8900.8.camel@Linuxdev4-laptop/#118378
+The original problem needs another way to solve.
+
+Fixes: 36a15e1cb134 ("net: usb: ax88179_178a needs FLAG_SEND_ZLP")
