I do not like that we have magic constants in the .hugepages that are<br>
not self describing. I would treat the hugetltbfs just as we treat<br>
devfs, that would be:<br>
<br>
#define MNTPOINT "hugetlbfs/"<br>
#define HUGEFILE MNTPOINT "hugefile"<br>
<br>
static int huge_fd;<br>
<br>
static void setup(void)<br>
{<br>
huge_fd = tst_creat_unlinked(HUGEFILE);<br>
...<br>
}<br>
<br>
static void cleanup(void)<br>
{<br>
if (huge_fd > 0)<br>
SAFE_CLOSE(huge_fd);<br>
}<br>
<br>
static struct tst_test test = {<br>
...<br>
.mntpoint = MNTPOINT,<br>
.needs_hugetlbfs = 1,<br>
.setup = setup,<br>
.cleanup = cleanup,<br>
...<br>
}<br>
<br>
<br>
What do you think?<br></blockquote><div><br></div><div class="gmail_default" style="font-size:small">+1 Looks good, this treats it as an FS and is separated from the hugepage usage.</div><div class="gmail_default" style="font-size:small"><br></div></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div>Regards,<br></div><div>Li Wang<br></div></div></div></div>
