Hello fellow kernel hackers,
I am currently considering tackling the following item
from the TODO list in the drivers/staging/exfat directory:
Fix (thing)->flags to not use magic numbers - multiple
offenders
I am having some difficulty figuring out what the flag bits
of the following two structs, defined in exfat.h, mean:
/* directory structure */
struct chain_t {
u32 dir;
s32 size;
u8 flags;
};
struct file_id_t {
struct chain_t dir;
s32 entry;
u32 type;
u32 attr;
u32 start_clu;
u64 size;
u8 flags;
s64 rwoffset;
s32 hint_last_off;
u32 hint_last_clu;
};
Are the bit specifications defined somewhere in the
linux kernel or online? Any guidance on how to go about figuring
them out would be much appreciated.

Probably not worth doing. See the patches from Namjae Jeon recently
which entirely replace this filesystem.
