Reiser4 breaks (Debian's ?) module-init-tools

[Pierre Etchemaite]

        Hi,

On an (almost) fully Reiser4 system, /etc/modprobe.d/ contents seem to
be disregarded. When tracing modprobe, each file in this directory is
opened as a directory, that looks a lot like the Apache
compatibility bug.

open("/etc/modprobe.d/autofs", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 4
fstat64(4, {st_mode=S_IFREG|0644, st_size=64, ...}) = 0
fcntl64(4, F_SETFD, FD_CLOEXEC)         = 0
getdents64(4, 0x8063e3c, 65536)         = -1 ENOTDIR (Not a directory)
close(4)                                = 0

Looking closer, it's not limited to that directory:

open("/lib/modules/2.6.8.1/modules.alias", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=27353, ...}) = 0
fcntl64(3, F_SETFD, FD_CLOEXEC)         = 0
getdents64(3, 0x804f0ac, 65536)         = -1 ENOTDIR (Not a directory)
close(3)                                = 0

Yes, it fixes the problem (as expected).

Are you sure they aren't more programs (almost) silently failing ?

What about a patch that logs processes running getdents() on regular
file descriptors, etc. ?

BR,
Pierre.
