Given that this is converting to darwin's statfs structure, is it okay if these stay omitted? > > > /* Converts proxy_stat structure to VFS stat structure */ > > @@ -143,12 +148,18 @@ static void prstat_to_stat(struct stat *stbuf, > > ProxyStat *prstat) stbuf->st_size = prstat->st_size; > > stbuf->st_blksize = prstat->st_blksize; > > stbuf->st_blocks = prstat->st_blocks; > > - stbuf->st_atim.tv_sec = prstat->st_atim_sec; > > Where did that go to? ^- > Unless I'm mistaken, I think this logic should still be present. Pre-patch, it's ordered so it runs through sec and nsec each for atime, mtime, and ctime respectively. To handle the darwin logic more cleanly, it's now broken out so it does _sec first, and then only needs one #ifdef to handle the two _nsec cases. > > > - stbuf->st_atim.tv_nsec = prstat->st_atim_nsec; > > + stbuf->st_atime = prstat->st_atim_sec; > > stbuf->st_mtime = prstat->st_mtim_sec; > > - stbuf->st_mtim.tv_nsec = prstat->st_mtim_nsec; > > stbuf->st_ctime = prstat->st_ctim_sec; > > +#ifdef CONFIG_DARWIN > > + stbuf->st_atimespec.tv_nsec = prstat->st_atim_nsec; > > + stbuf->st_mtimespec.tv_nsec = prstat->st_mtim_nsec; > > + stbuf->st_ctimespec.tv_nsec = prstat->st_ctim_nsec; > > +#else > > + stbuf->st_atim.tv_nsec = prstat->st_atim_nsec; > > + stbuf->st_mtim.tv_nsec = prstat->st_mtim_nsec; > > stbuf->st_ctim.tv_nsec = prstat->st_ctim_nsec; > > +#endif > > } > > > > /* > > diff --git a/hw/9pfs/9p-synth.c b/hw/9pfs/9p-synth.c > > index b38088e066..4a4a776d06 100644 > > --- a/hw/9pfs/9p-synth.c > > +++ b/hw/9pfs/9p-synth.c > > @@ -427,7 +427,9 @@ static int synth_statfs(FsContext *s, V9fsPath > *fs_path, > > stbuf->f_bsize = 512; > > stbuf->f_blocks = 0; > > stbuf->f_files = synth_node_count; > > +#ifndef CONFIG_DARWIN > > stbuf->f_namelen = NAME_MAX; > > +#endif > > return 0; > > } > > As mentioned above. > > > diff --git a/hw/9pfs/9p.c b/hw/9pfs/9p.c > > index 9c63e14b28..f4f0c200c7 100644 > > --- a/hw/9pfs/9p.c > > +++ b/hw/9pfs/9p.c > > @@ -1313,11 +1313,17 @@ static int stat_to_v9stat_dotl(V9fsPDU *pdu, > const > > struct stat *stbuf, v9lstat->st_blksize = stat_to_iounit(pdu, stbuf); > > v9lstat->st_blocks = stbuf->st_blocks; > > v9lstat->st_atime_sec = stbuf->st_atime; > > - v9lstat->st_atime_nsec = stbuf->st_atim.tv_nsec; > > v9lstat->st_mtime_sec = stbuf->st_mtime; > > - v9lstat->st_mtime_nsec = stbuf->st_mtim.tv_nsec; > > v9lstat->st_ctime_sec = stbuf->st_ctime; > > +#ifdef CONFIG_DARWIN > > + v9lstat->st_atime_nsec = stbuf->st_atimespec.tv_nsec; > > + v9lstat->st_mtime_nsec = stbuf->st_mtimespec.tv_nsec; > > + v9lstat->st_ctime_nsec = stbuf->st_ctimespec.tv_nsec; > > +#else > > + v9lstat->st_atime_nsec = stbuf->st_atim.tv_nsec; > > + v9lstat->st_mtime_nsec = stbuf->st_mtim.tv_nsec; > > v9lstat->st_ctime_nsec = stbuf->st_ctim.tv_nsec; > > +#endif > > /* Currently we only support BASIC fields in stat */ > > v9lstat->st_result_mask = P9_STATS_BASIC; > > > > @@ -3519,9 +3525,15 @@ static int v9fs_fill_statfs(V9fsState *s, V9fsPDU > > *pdu, struct statfs *stbuf) f_bavail = stbuf->f_bavail / bsize_factor; > > f_files = stbuf->f_files; > > f_ffree = stbuf->f_ffree; > > +#ifdef CONFIG_DARWIN > > + fsid_val = (unsigned int)stbuf->f_fsid.val[0] | > > + (unsigned long long)stbuf->f_fsid.val[1] << 32; > > + f_namelen = MAXNAMLEN; > > +#else > > fsid_val = (unsigned int) stbuf->f_fsid.__val[0] | > > (unsigned long long)stbuf->f_fsid.__val[1] << 32; > > f_namelen = stbuf->f_namelen; > > +#endif > > > > return pdu_marshal(pdu, offset, "ddqqqqqqd", > > f_type, f_bsize, f_blocks, f_bfree, > > >
