You can hit the same problems with ioctls or even with normal operation of the device. And prohibiting the extension of whitelists is gonna increase the usage of unpriv_sgio and less-secure userspace whitelists. Anvil, meet hammer. For example: if (bdev_write_same(bdev)) { unsigned char bdn[BDEVNAME_SIZE]; if (!blkdev_issue_write_same(bdev, sector, nr_sects, gfp_mask, ZERO_PAGE(0))) return 0; bdevname(bdev, bdn); pr_err("%s: WRITE SAME failed.

Unfortunately, mvmdio lives in drivers/net/ethernet/marvell/mvmdio.c which I should have noticed before. Whatever is good for you guys, but we should probably start normalizing this now before more mdio drivers get merged alongside their corresponding ethernet MAC users. </pre> Florian Fainelli 2013-05-24T09:42:30 http://permalink.gmane.org/gmane.linux.kernel/1496207 <pre> we should check kzalloc, avoid to hit oops Signed-off-by: Libo Chen &lt;libo.chen&lt; at &gt;huawei.com&gt; --- drivers/scsi/megaraid.c | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) instead of checking scmd-&gt;device, sdev is more appropriate. diff --git a/drivers/scsi/megaraid.c b/drivers/scsi/megaraid.c index 846f475..6b623cb 100644 --- a/drivers/scsi/megaraid.c +++ b/drivers/scsi/megaraid.c &lt; at &gt;&lt; at &gt; -4161,6 +4161,10 &lt; at &gt;&lt; at &gt; mega_internal_command(adapter_t *adapter, megacmd_t *mc, mega_passthru *pthru) memset(scb, 0, sizeof(scb_t)); sdev = kzalloc(sizeof(struct scsi_device), GFP_KERNEL); +if (sdev) { +scsi_free_command(GFP_KERNEL, scmd); +return -ENOMEM; +} scmd-&gt;device = sdev; memset(adapter-&gt;int_cdb, 0, sizeof(adapter-&gt;int_cdb)); </pre> Libo Chen 2013-05-24T09:40:34 http://permalink.gmane.org/gmane.linux.kernel/1496206 <pre>Hi Linus !

However, I'd like to make the argument that it is desirable to have each proc mount, even those that reference the same namespace, have a different superblock. One option that I intend to add is the ability to specify which pid namespace proc is mounted for, rather than forcing the current one. If this were to be added, it wouldn't work to share superblocks, as that would prevent remounts of proc from switching which namespace that the refer to (or that is my understanding, which may be incorrect). Considering the small number of proc mounts that tend to be around anyway, perhaps this outweighs the drawbacks. Let me know what you think.
