2020-01-26cifs: Fix return value in __update_cache_entryYueHaibing
copy_ref_data() may return error, it should be returned to upstream caller. Fixes: 03535b72873b ("cifs: Avoid doing network I/O while holding cache lock") Signed-off-by: YueHaibing <yuehaibing@huawei.com> Signed-off-by: Steve French <stfrench@microsoft.com>
2020-01-26cifs: Avoid doing network I/O while holding cache lockPaulo Alcantara (SUSE)
When creating or updating a cache entry, we need to get an DFS referral (get_dfs_referral), so avoid holding any locks during such network operation. To prevent that, do the following: * change cache hashtable sync method from RCU sync to a read/write lock. * use GFP_ATOMIC in memory allocations.

2020-01-26cifs: Fix potential deadlock when updating vol in cifs_reconnect()Paulo Alcantara (SUSE)
We can't acquire volume lock while refreshing the DFS cache because cifs_reconnect() may call dfs_cache_update_vol() while we are walking through the volume list. To prevent that, make vol_info refcounted, create a temp list with all volumes eligible for refreshing, and then use it without any locks held. Besides, replace vol_lock with a spinlock and protect cache_ttl from concurrent accesses or changes.

2020-01-26io_uring: don't cancel all work on process exitJens Axboe
If we're sharing the ring across forks, then one process exiting means that we cancel ALL work and prevent future work. This is overly restrictive. As long as we cancel the work associated with the files from the current task, it's safe to let others persist. Normal fd close on exit will still wait (and cancel) pending work.

2020-01-26block: allow partitions on host aware zone devicesChristoph Hellwig
Host-aware SMR drives can be used with the commands to explicitly manage zone state, but they can also be used as normal disks. In the former case it makes perfect sense to allow partitions on them, in the latter it does not, just like for host managed devices. Add a check to add_partition to allow partitions on host aware devices, but give up any zone management capabilities in that case, which also catches the previously missed case of adding a partition vs just scanning it. Because sd can rescan the attribute at runtime it needs to check if a disk has partitions, for which a new helper is added to genhd.h.

2020-01-26afs: Fix characters allowed into cell namesDavid Howells
The afs filesystem needs to prohibit certain characters from cell names, such as '/', as these are used to form filenames in procfs, leading to the following warning being generated: WARNING: CPU: 0 PID: 3489 at fs/proc/generic.c:178 Fix afs_alloc_cell() to disallow nonprintable characters, '/', '@' and names that begin with a dot. Remove the check for "@cell" as that is then redundant. This can be tested by running: echo add foo/.bar 1.2.3.4 >/proc/fs/afs/cells Note that we will also need to deal with: - Names ending in ".invalid" shouldn't be passed to the DNS. - Names that contain non-valid domainname chars shouldn't be passed to the DNS. - DNS replies that say "your-dns-needs-immediate-attention.<gTLD>" and replies containing A records that say 127.0.53.53 should be considered invalid.

2020-01-26rtw88: use shorter delay time to poll PS stateYan-Hsuan Chuang
When TX packet arrives, driver should leave deep PS state to make sure the DMA is working. After requested to leave deep PS state, driver needs to poll the PS state to check if the mode has been changed successfully. The driver used to check the state of the hardware every 20 msecs, which means upon the first failure of state check, the CPU is delayed 20 msecs for next check. This is harmful for some time-sensitive applications such as media players. So, use shorter delay time each check from 20 msecs to 100 usecs. The state should be changed in several tries. But we still need to reserve ~15 msecs in total in case of the state just took too long to be changed successfully. If the states of driver and the hardware is not synchronized, the power state could be locked forever, which mean we could never enter/leave the PS state.

Commit 262f2b53f679 ("brcmfmac: call brcmf_attach() just before calling brcmf_bus_started()") changed the initialization order of the brcmfmac SDIO driver. Unfortunately since brcmf_sdiod_intr_register() is now called before the sdiodev->bus_if initialization, it reads the wrong chip ID and fails to initialize the GPIO on brcm43362.
