From a86f009f106cba322c608785e09c8b5be8ffe8bb Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Wed, 23 May 2018 14:46:53 +0200 Subject: libceph: allocate the locator string with GFP_NOFAIL calc_target() isn't supposed to fail with anything but POOL_DNE, in which case we report that the pool doesn't exist and fail the request with -ENOENT. Doing this for -ENOMEM is at the very least confusing and also harmful -- as the preceding requests complete, a short-lived locator string allocation is likely to succeed after a wait. (We used to call ceph_object_locator_to_pg() for a pi lookup. In theory that could fail with -ENOENT, hence the "ret != -ENOENT" warning being removed.)
