Subject: [pve-devel] [PATCH storage v3 09/13] common: introduce common module
Date: Thu, 19 Dec 2024 11:43:12 +0100 [thread overview]
Message-ID: <20241219104316.35329-10-f.ebner@proxmox.com> (raw)
In-Reply-To: <20241219104316.35329-1-f.ebner@proxmox.com>
From: Max Carrara <m.carrara@proxmox.com>
This module's purpose is to provide shared functions, constants, etc.
for storage plugins and storage-related operations.
It starts out with a align_size_up() function, that will (initially)
be used for volume import.
Originally-by: Max Carrara <m.carrara@proxmox.com>
[FE: start out with a different function for my use case
fixup Makefile]

+
+PVE::Storage::Common - Shared functions and utilities for storage plugins and storage operations
+
+=head1 DESCRIPTION
+
+This module contains common subroutines that are mainly to be used by storage
+plugins. This module's submodules contain subroutines that are tailored towards
+a more specific or related purpose.
+
+Functions concerned with storage-related C<PVE::SectionConfig> things, helpers
+for the C<PVE::Storage> API can be found in this module. Functions that can't
+be grouped in a submodule can also be found here.

+
+ $aligned_size = align_size_up($size, $granularity)
+
+Returns the next size bigger than or equal to C<$size> that is aligned with a
+granularity of C<$granularity>. Prints a message if the aligned size is not
+equal to the aligned size.
