Hi Namjae,

The client cannot use `SidBuffer[32]` because the size of `SidBuffer[]` 
on the client side is not necessarily 32.

在 2026/3/10 09:02, Namjae Jeon 写道:
>>          /* SidBuffer contain two sids (UNIX user sid(16), UNIX group sid(16)) */
>>          u8 SidBuffer[32];
>>          __le32 name_len;
>>          u8 name[];
> These 3 fields should be removed and use flex array in struct file_posix_info.
> And why can't smb2_posix_info move to /smb/common?
