[PATCH v6 0/2] erofs: set block size to the on-disk block size

From: Jingbo Xu
Date: Mon Mar 13 2023 - 09:53:26 EST


changes since v5:
- patch 1: calculate len of crc range correctly considering when
blocksize <= EROFS_SUPER_OFFSET, i.e. blocksize is 512 or 1024 bytes
(Gao Xiang)
- patch 2: remove sbi->dirblkbits for now (Gao Xiang)

changes since v4:
- patch 1: convert several remained call sites of sb->s_blocksize_bits
to erofs_blknr() and erofs_pos() (Yue Hu)
- patch 2: revise comment for blkszbits and dirblkbits (Yue Hu)

changes since v3:
- patch 1: remove redundant newline when printing messages (Gao Xiang)
- patch 2: introduce dirblkbits in on-disk superblock and disable this
feature for now, so that the current kernel won't break with the image
with this feature enabled later (Gao Xiang)
