Subject: [f2fs-dev] [PATCH] f2fs: subtract current_reserved_blocks from total
Date: Tue, 4 Mar 2025 11:20:41 -0800 [thread overview]
Message-ID: <20250304192041.4048741-1-daeho43@gmail.com> (raw)
From: Daeho Jeong <daehojeong@google.com>
current_reserved_blocks is not allowed to utilize. For some zoned
storage devices, vendors will provide extra space which was used for
device level GC than specs and we will use this space for filesystem
level GC. This extra space should not be shown to users, otherwise,
users will see not standardized size number like 530GB, not 512GB.
