2021-12-24crypto: qat - add the adf_get_pmisc_base() helper functionMarco Chiappero
Add and use the new helper function adf_get_pmisc_base() where convenient. Also: - remove no longer shared variables - leverage other utilities, such as GET_PFVF_OPS(), as a consequence - consistently use the "pmisc_addr" name for the returned value of this new helper Signed-off-by: Marco Chiappero <marco.chiappero@intel.com> Co-developed-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Signed-off-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Reviewed-by: Fiona Trahe <fiona.trahe@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2021-12-24crypto: qat - support the reset of ring pairs on PFMarco Chiappero
Add support for triggering a HW reset of a specific ring pair. Being a device specific feature, add it to the hw_device_data struct. This feature is supported only by QAT GEN4 devices.

2021-12-23ext4: use ext4_journal_start/stop for fast commit transactionsHarshad Shirwadkar
This patch drops all calls to ext4_fc_start_update() and ext4_fc_stop_update(). To ensure that there are no ongoing journal updates during fast commit, we also make jbd2_fc_begin_commit() lock journal for updates. This way we don't have to maintain two different transaction start stop APIs for fast commit and full commit. This patch doesn't remove the functions altogether since in future we want to have inode level locking for fast commits.

2021-12-23jffs2: GC deadlock reading a page that is used in jffs2_write_begin()Kyeong Yoo
GC task can deadlock in read_cache_page() because it may attempt to release a page that is actually allocated by another task in jffs2_write_begin(). The reason is that in jffs2_write_begin() there is a small window a cache page is allocated for use but not set Uptodate yet. This ends up with a deadlock between two tasks: 1) A task (e.g. file copy) - jffs2_write_begin() locks a cache page - jffs2_write_end() tries to lock "alloc_sem" from jffs2_reserve_space() <-- STUCK 2) GC task (jffs2_gcd_mtd3) - jffs2_garbage_collect_pass() locks "alloc_sem" - try to lock the same cache page in read_cache_page() <-- STUCK So to avoid this deadlock, hold "alloc_sem" in jffs2_write_begin() while reading data in a cache page.

2021-12-23ubifs: Export filesystem error countersStefan Schaeckeler
Not all ubifs filesystem errors are propagated to userspace. Export bad magic, bad node and crc errors via sysfs. This allows userspace to notice filesystem errors: /sys/fs/ubifs/ubiX_Y/errors_magic /sys/fs/ubifs/ubiX_Y/errors_node /sys/fs/ubifs/ubiX_Y/errors_crc The counters are reset to 0 with a remount.

2021-12-23drm/etnaviv: consider completed fence seqno in hang checkLucas Stach
Some GPU heavy test programs manage to trigger the hangcheck quite often. If there are no other GPU users in the system and the test program exhibits a very regular structure in the commandstreams that are being submitted, we can end up with two distinct submits managing to trigger the hangcheck with the FE in a very similar address range. This leads the hangcheck to believe that the GPU is stuck, while in reality the GPU is already busy working on a different job. To avoid those spurious GPU resets, also remember and consider the last completed fence seqno in the hang check.
