MAINTAINERS

SPDK Component Maintainers
==========================

This file lists the component maintainers for supported components in SPDK.
It also provides status for orphaned and/or obsolete components which may
be removed from SPDK in future releases. Please see deprecation.md for
the schedule of such removals.

Component maintainer does not equal core maintainer. All core maintainers
will likely maintain several components, but not all component maintainers
are necessarily core maintainers.

Core maintainers should wait for votes from component maintainers before
merging patches affecting that component. -1 votes from component maintainers
are effectively blocking votes. Core maintainers remain as final arbiter on
patch merges, and will only override component maintainers under
exceptional circumstances. Core maintainers may also merge patches without
component maintainer votes if the component maintainers have not
reviewed and voted on patches within a reasonable amount of time.

Component maintainers are responsible for the overall design, support
and maintenance for the component. This includes resolving GitHub issues,
responding to questions on Slack and e-mail, and maintaining tests and
CI infrastructure for running those tests. This infrastructure may just
be public GitHub runners but may also require self-hosted runners depending
on the hardware requirements.

Do not use this list for purposes of sending private messages to
component maintainers via Slack or e-mail. Keep discussion on public
communication channels and tag component maintainers in those messages as
necessary.

Descriptions of section entries:

M: Maintainer's Full Name <address@domain>
   Multiple maintainers per component are acceptable.
S: Status of the component. Valid values are "Supported", "Orphaned", and
   "Obsolete".
F: Files and directories with wildcard patterns.
   A trailing slash includes all files and subdirectory files.
   Wildcards may be used to specify multiple files or multiple directories.
   One pattern per line. Multiple F: lines acceptable.
X: Files and directories exclusion, same rules as F:
