Hi,
In the PetaLinux 0.30 distribution, it appears that all of the instances
of statvfs.h contain the following bug:
enum
{
ST_RDONLY = 1, /* Mount read-only. */
...
ST_NOATIME = 1024, /* Do not update access times. */
# define ST_NOATIME ST_NOATIME
ST_NODIRATIME /* Do not update directory access times. */
...
};
...which defines ST_NODIRATIME as 1025 instead of the 2048 it is supposed
to be.
The attached patch will fix the header files, but the wrong definition is
also compiled into all the statvfs functions in all the libc.a files
under tools/linux-i386/microblaze-uclinux-tools/microblaze-uclinux/lib.
Without binary edits to fix the object code, the patch doesn't do any
good because filesystems mounted with NODIRATIME set will appear to have
NOATIME and RDONLY instead.
It looks like this bug was fixed in uClibc v0.9.29. Petalinux-0.30
appears to use 0.9.27. It would be nice if a more recent uClibc could be
included in the next PL release. The uClibc folks seem to be on target to
release 0.9.30 by the end of the month.
Regards,
Steve
