Looks good! It seems like a lot of inefficient code has been cleaned up overall. BTW, only one thing about the patch 'reduce FAT chain traversal', there may be confusion as the concepts of 'dir' and 'entry' within 'struct exfat_dir_entry' have changed from what we previously understood. To clarify the changed concept, how about leaving an inline description for each of 'dir' and 'entry' in 'struct exfat_dir_entry'? > > fs/exfat/dir.c | 38 ++++------- > fs/exfat/exfat_fs.h | 2 + > fs/exfat/inode.c | 2 +- > fs/exfat/namei.c | 155 +++++++++++++++++++------------------------- > 4 files changed, 82 insertions(+), 115 deletions(-) > > -- > 2.43.0
