However instead of having kwazillion new readdir()/getdents() syscalls, lets merge that into LFS patch contained getdents64().
ftp://mea.tmt.tele.fi/linux/LFS/ lfs-patches-v0.21-base-2.3.27-pre1-G-readdir64.diff
struct linux_dirent64 { __u64 d_ino; /* 64 bits *should* be enough */ __u32 d_off; /* position within directory */ __u32 d_flags; /* what is stored in d_data[] */ __u32 d_data[8]; /* for future extensions */ __u16 d_reclen; char d_name[1]; /* We must not include limits.h! */ };
asmlinkage long sys_getdents64( unsigned int fd, struct linux_dirent64 *dirent, unsigned int count, long flags ) { ... }
Unlike sys_getdents(), original behaviour happens only when 'flags' is zero, d_flags, and d_data[] can be filled in guidance of what 'flags' tells.
