f2fs: fix to calculate dirty data during has_not_enough_free_secs()

2025-08-15T10:08:59+00:00

[ Upstream commit e194e140ab7de2ce2782e64b9e086a43ca6ff4f2 ] In lfs mode, dirty data needs OPU, we'd better calculate lower_p and upper_p w/ them during has_not_enough_free_secs(), otherwise we may encounter out-of-space issue due to we missed to reclaim enough free section w/ foreground gc.

f2fs: fix start segno of large section

2024-08-03T06:54:35+00:00

[ Upstream commit 8c409989678e92e4a737e7cd2bb04f3efb81071a ] get_ckpt_valid_blocks() checks valid ckpt blocks in current section. It counts all vblocks from the first to the last segment in the large section. However, START_SEGNO() is used to get the first segno in an SIT block. This patch fixes that to get the correct start segno.
