Description

A flaw was found in the F2FS file system in the Linux Kernel due to incorrect handling of compression and garbage collection. The CURSEG_ALL_DATA_ATGC flag was mistakenly assigned to COMPR_ADDR for pages marked with the garbage collection flag (gcing). This led to an assertion failure (BUG_ON) at fs/f2fs/segment.c:3589. This issue occurs during file operations involving compression and truncation. The fix ensures proper flag management, preventing the BUG_ON and maintaining file system stability.
