[PATCH openEuler-1.0-LTS] nvme: Assign subsys instance from first ctrl
by Chen Taotao 09 Jun '22

09 Jun '22

mainline inclusion from mainline-5.3.0-rc3 commit 733e4b69d508d03c20adfdcf4bd27abc60fae9cc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5986O CVE: NA -------------------------------- The namespace disk names must be unique for the lifetime of the subsystem. This was accomplished by using their parent subsystems' instances which were allocated independently from the controllers connected to that subsystem. This allowed name prefixes assigned to namespaces to match a controller from an unrelated subsystem, and has created confusion among users examining device nodes. Ensure a namespace's subsystem instance never clashes with a controller instance of another subsystem by transferring the instance ownership to the parent subsystem from the first controller discovered in that subsystem.

[PATCH] nvme: Assign subsys instance from first ctrl upstream 733e4b69
by Chen Taotao 06 Jun '22

06 Jun '22

The namespace disk names must be unique for the lifetime of the subsystem. This was accomplished by using their parent subsystems' instances which were allocated independently from the controllers connected to that subsystem. This allowed name prefixes assigned to namespaces to match a controller from an unrelated subsystem, and has created confusion among users examining device nodes. Ensure a namespace's subsystem instance never clashes with a controller instance of another subsystem by transferring the instance ownership to the parent subsystem from the first controller discovered in that subsystem.
