From 9f5067531c9b79318c4e48a933cb2694f53f3de2 Mon Sep 17 00:00:00 2001 From: Tomer Tayar Date: Sun, 26 May 2024 16:32:32 +0300 Subject: [PATCH] accel/habanalabs: return ENOMEM if less than requested pages were pinned EFAULT is currently returned if less than requested user pages are pinned. This value means a "bad address" which might be confusing to the user, as the address of the given user memory is not necessarily "bad". Modify the return value to ENOMEM, as "out of memory" is more suitable in this case.
