f2fs: revert summary entry count from 2048 to 512 in 16kb block support

2025-12-18T13:00:10+00:00

[ Upstream commit 7ee8bc3942f20964ad730871b885688ea3a2961a ]

The recent increase in the number of Segment Summary Area (SSA) entries
from 512 to 2048 was an unintentional change in logic of 16kb block
support. This commit corrects the issue.

To better utilize the space available from the erroneous 2048-entry
calculation, we are implementing a solution to share the currently
unused SSA space with neighboring segments. This enhances overall
SSA utilization without impacting the established 8MB segment size.

f2fs: Pass a folio to f2fs_submit_merged_write_cond()

2025-07-22T15:58:05+00:00

Most callers pass NULL, and the one that passes a page already has a
folio.  Also convert __submit_merged_write_cond() to take a folio.

f2fs: introduce is_cur{seg,sec}()

2025-07-09T18:02:20+00:00

There are redundant codes in IS_CUR{SEG,SEC}() macros, let's introduce
inline is_cur{seg,sec}() functions, and use a loop in it for cleanup.

Meanwhile, it enhances expansibility, as it doesn't need to change
is_cur{seg,sec}() when we add a new log header.
