| - | * If no comments or warnings, Kalle applies the patch to ath-next branch and sends a "Thanks, applied" reply. | + | * If no comments or warnings, Kalle applies the patch either to ath-current branch (for critical fixes) or to ath-next branch (new features, low priority fixes) and sends a "Thanks, applied" reply. |
| - | * Kalle merges ath-next to master branch immeadiately after the patch is applies. | + | * Kalle merges ath-next and ath-current to master branch immeadiately after the patch is applied. |

| + | As a rough estimate it takes 2-4 months for a patch to propagate from ath-next to an official Linux release. | ||
| + | To clarify the meaning with ath-current and ath-next let's take a concrete example: let's say that the latest release from Linux is v4.9-rc2. If a patch is applied to ath-current it will most like be in v4.9-rc4 or v4.9-rc5 (usually it takes a minimum of one week to get to Linus' tree, sometimes more). But if the patch is applied to ath-next the first release it will be in is v4.10-rc1. | ||
