In80e7342ea8(reftable/stack: allow locking of outdated stacks, 2024-09-24), the `REFTABLE_STACK_NEW_ADDITION_RELOAD` was introduced so that callers of `reftable_stack_init_addition()` can also reload the stack if there was a concurrent update made before the lock was obtained. Then16684b6fae(refs/reftable: always reload stacks when creating lock, 2025-08-12) updated all of the remaining call-sites to propagate this flag to ensure that we always reload the stack whenever there was a concurrent update. As all calls to `reftable_stack_init_addition()` inevitably propagate the flag, it is safe to remove the flag and its associated code and make the reloading of the stack the default flow. This makes it easier to follow the flow and simplifies the logic. The only exceptions are: 1. Unit tests, where we explicitly do not propagate the flag. These tests are now modified with the new status quo. 2. `reftable_stack_clean()`, which was propagating 0 to `reftable_stack_new_addition()` but was then manually reloading the stack after. Here the new flow will achieve the same, while also allowing us to remove the manual reload. This also makes two checks for 'REFTABLE_OUTDATED_ERROR' redundant, so remove them also.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.adoc
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
