From dc31f99be6822a16b119a1f145555757c6761b36 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 9 Jan 2018 12:19:38 +1100 Subject: [PATCH] staging: lustre: use kmalloc for allocating ksock_tx The size of the data structure is primarily controlled by the iovec size, which is limited to 256. Entries in this vector are 12 bytes, so the whole will always fit in a page. So it is safe to use kmalloc (kvmalloc not needed). So replace LIBCFS_ALLOC with kmalloc.
