Based on vijay's inputs I checked in fuse-brige and this is what I see:
1162 if (fsi->valid & FATTR_FH &&
1163 !(fsi->valid & (FATTR_ATIME|FATTR_MTIME))) {
1164 /* We need no loc if kernel sent us an fd and
1165 * we are not fiddling with times */
1166 state->fd = FH_TO_FD (fsi->fh);
(gdb)
1167 fuse_resolve_fd_init (state, &state->resolve, state->fd);
1168 } else {
1169 fuse_resolve_inode_init (state, &state->resolve, finh->nodeid);
1170 }
1171
(gdb) p fsi->valid
$4 = 1
(gdb) p (fsi->valid & FATTR_FH)
$5 = 0
(gdb)
fsi->valid doesn't have FATTR_FH. Who is supposed to set it?
