Subject: [PATCH v3] f2fs: fix CURSEG_HOT_DATA left space check
Date: Wed, 6 Aug 2025 20:32:36 +0800 [thread overview]
Message-ID: <20250806123236.4389-1-masonzhang.linuxer@gmail.com> (raw)
This fix combines the space check for data_blocks and dent_blocks when
verifying HOT_DATA segment capacity, preventing potential insufficient
space issues during checkpoint.
Fixes: bf34c93d2645 ("f2fs: check curseg space before foreground GC")
