[f2fs-dev] [RFC PATCH 2/2] f2fs-tools: redefine MAX_SIT_BITMAP_SIZE

During mkfs, segment_count_sit is calculated using ALIGN and SEG_ALIGN, which are both upward. Then, in some extreme scenarios, such as 16TB, sit_ver_bitmap_bytesize got from segment_count_sit will exceed MAX_SIT_BITMAP_SIZE, which is calculated in a downward method. Unify the two calculating

[f2fs-dev] [RFC PATCH 1/2] libf2fs: limit the total size up to 16T

F2FS can support 16T bytes at most. Limit the config.total_sectors so that most parameters calculated according to it in sb/cp can be limited correctly too. Signed-off-by: Junling Zheng --- lib/libf2fs.c | 5 + 1 file changed, 5 insertions(+) diff --git
