[PATCH 1/1] [media] tw686x: silent -Wformat-security warning

Using sprintf() with a non-literal string makes some compiler complain when building with -Wformat-security (eg. clang reports "format string is not a string literal (potentially insecure)"). Here sprintf() format parameter is indirectly a literal string so there is no security issue. Nevertheles

[PATCH 2/2] z3fold: fix locking issues

Commit 570931c ("z3fold: use per-page spinlock") introduced locking issues in reclaim function reported in [1] and [2]. This patch addresses these issues, also fixing the check for empty lru list (it was only checked once, while it should be checked every time we want to get the last lru entry). [

[PATCH 1/1] libnvdimm, namespace: fix the type of name variable

In create_namespace_blk(), the local variable "name" is defined as an array of NSLABEL_NAME_LEN pointers: char *name[NSLABEL_NAME_LEN]; This variable is then used in calls to memcpy() and kmemdup() as if it were char[NSLABEL_NAME_LEN]. Remove the star in the variable definition to makes it lo

[PATCH 1/2] z3fold: fix header size related issues

Currently the whole kernel build will be stopped if the size of struct z3fold_header is greater than the size of one chunk, which is 64 bytes by default. This patch instead defines the offset for z3fold objects as the size of the z3fold header in chunks. Fixed also are the calculation of num_free_

[PATCH 0/2] z3fold fixes

Here come 2 patches with z3fold fixes for chunks counting and locking. As commit 50a50d2 ("z3fold: don't fail kernel build is z3fold_header is too big") was NAK'ed [1], I would suggest that we removed that one and the next z3fold commit cc1e9c8 ("z3fold: discourage use of pages that weren't comp
