* ARM: dts: sun8i: Add eMMC dt node on Orangepi Plus boardsHans de Goede2016-03-27
| | | | | | | | | | | | | | | | | | | | | | | | The Orangepi Plus has a 16GB eMMC, the vcc, the lack of pull-ups and the use of the hw-reset pin have all been verified with the board schematic. With this dts node for mmc2, the eMMC runs at the following ios settings: clock: 52000000 Hz vdd: 21 (3.3 ~ 3.4 V) bus mode: 2 (push-pull) chip select: 0 (don't care) power mode: 2 (on) bus width: 3 (8 bits) timing spec: 8 (mmc DDR52) signal voltage: 0 (3.30 V) driver type: 0 (driver type B) Note the mmcblk1boot0/boot1 partitions are unused as the BROM will load the SPL from 8k from the start of the main blockdev, just as with a regular sdcard in mmc0.

* ARM: dts: sun8i: Add wifi dt node on Orangepi Plus boardsHans de Goede2016-03-27
| | | | | | | | | | | | | | | | | | | The Orangepi Plus and Orangepi Plus 2 have a realtek rtl8189etv sdio wifi chip. This commit adds a device-tree node to power it up, so that the mmc subsys can scan it, and enables the mmc controller which is connected to it. Note that this just makes the wifi controller show up as a sdio device. In order for it to work a compatible sdio driver is necessary, an out of tree driver is available here: https://github.com/jwrdegoede/rtl8189ES_linux/ Binding the driver is not done through device tree, but through sdio vendor- and device-id, so it can safely be enabled in devicetree without having a driver upstream yet.

| * ceph: use lookup request to revalidate dentryYan, Zheng2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If dentry has no lease, ceph_d_revalidate() previously return 0. This causes VFS to invalidate the dentry and create a new dentry for later lookup. Invalidating a dentry also detach any underneath mount points. So mount point inside cephfs can disapear mystically (even the mount point is not modified by other hosts). The fix is using lookup request to revalidate dentry without lease. This can partly solve the mount points disapear issue (as long as the mount point is not modified by other hosts) Signed-off-by: Yan, Zheng <zyan@redhat.com>

| * ceph: fix security xattr deadlockYan, Zheng2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When security is enabled, security module can call filesystem's getxattr/setxattr callbacks during d_instantiate(). For cephfs, d_instantiate() is usually called by MDS' dispatch thread, while handling MDS reply. If the MDS reply does not include xattrs and corresponding caps, getxattr/setxattr need to send a new request to MDS and waits for the reply. This makes MDS' dispatch sleep, nobody handles later MDS replies. The fix is make sure lookup/atomic_open reply include xattrs and corresponding caps. So getxattr can be handled by cached xattrs. This requires some modification to both MDS and request message. (Client tells MDS what caps it wants; MDS encodes proper caps in the reply) Smack security module may call setxattr during d_instantiate(). Unlike getxattr, we can't force MDS to issue CEPH_CAP_XATTR_EXCL to us. So just make setxattr return error when called by MDS' dispatch thread. Signed-off-by: Yan, Zheng <zyan@redhat.com>

| | | | | | | | | | | | | | | | | | Readdir cache uses page cache to save dentry pointers. When adding dentry pointers to middle of a page, we need to make sure the page already exists. Otherwise the beginning part of the page will be invalid pointers. Signed-off-by: Yan, Zheng <zyan@redhat.com>

| * ceph: kill ceph_empty_snapcIlya Dryomov2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ceph_empty_snapc->num_snaps == 0 at all times. Passing such a snapc to ceph_osdc_alloc_request() (possibly through ceph_osdc_new_request()) is equivalent to passing NULL, as ceph_osdc_alloc_request() uses it only for sizing the request message. Further, in all four cases the subsequent ceph_osdc_build_request() is passed NULL for snapc, meaning that 0 is encoded for seq and num_snaps and making ceph_empty_snapc entirely useless. The two cases where it actually mattered were removed in commits 860560904962 ("ceph: avoid sending unnessesary FLUSHSNAP message") and 23078637e054 ("ceph: fix queuing inode to mdsdir's snaprealm").

| | | | | | | | | | | | | | | | | | | | This patch makes ceph_writepages_start() try using single OSD request to write all dirty pages within a strip unit.

| | | | | | | | | | | | | | | | | | | | This helper duplicates last extent operation in OSD request, then adjusts the new extent operation's offset and length.

| * libceph: enable large, variable-sized OSD requestsIlya Dryomov2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turn r_ops into a flexible array member to enable large, consisting of up to 16 ops, OSD requests. The use case is scattered writeback in cephfs and, as far as the kernel client is concerned, 16 is just a made up number. r_ops had size 3 for copyup+hint+write, but copyup is really a special case - it can only happen once. ceph_osd_request_cache is therefore stuffed with num_ops=2 requests, anything bigger than that is allocated with kmalloc(). req_mempool is backed by ceph_osd_request_cache, which means either num_ops=1 or num_ops=2 for use_mempool=true - all existing users (ceph_writepages_start(), ceph_osdc_writepages()) are fine with that.
