As the value here is a multiple of 1000, use secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication. This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with the following Coccinelle rules: @@ constant C; @@ - msecs_to_jiffies(C * 1000) + secs_to_jiffies(C) @@ constant C; @@ - msecs_to_jiffies(C * MSEC_PER_SEC) + secs_to_jiffies(C) Link: https://lkml.kernel.org/r/20241210-converge-secs-to-jiffies-v3-18-ddfefd7e9f2a@linux.microsoft.com Signed-off-by: Easwar Hariharan <[email protected]> Reviewed-by: Christophe Leroy <[email protected]> Cc: Alexander Gordeev <[email protected]> Cc: Andrew Lunn <[email protected]> Cc: Anna-Maria Behnsen <[email protected]> Cc: Catalin Marinas <[email protected]> Cc: Christian Borntraeger <[email protected]> Cc: Daniel Mack <[email protected]> Cc: David Airlie <[email protected]> Cc: David S.

* livepatch/sample: Use the right type for the leaking data pointerPetr Mladek2020-01-171-2/+2
| | | | | | | | | | | | | The "leak" pointer, in the sample of shadow variable API, is allocated as sizeof(int). Let's help developers and static analyzers with understanding the code by using the appropriate pointer type.

* livepatch: samples: non static warnings fixNicholas Mc Guire2019-01-251-5/+6
| | | | | | | | | | | | | | Sparse reported warnings about non-static symbols. For the variables a simple static attribute is fine - for the functions referenced by livepatch via klp_func the symbol-names must be unmodified in the symbol table and the patchable code has to be emitted. The resolution is to attach __used attribute to the shared statically declared functions.

* livepatch: check kzalloc return valuesNicholas Mc Guire2018-12-181-0/+4
| | | | | | | | | | | | | | | kzalloc() return should always be checked - notably in example code where this may be seen as reference. On failure of allocation in livepatch_fix1_dummy_alloc() respectively dummy_alloc() previous allocation is freed (thanks to Petr Mladek <[email protected]> for catching this) and NULL returned.

* livepatch: introduce shadow variable APIJoe Lawrence2017-09-141-0/+224
Add exported API for livepatch modules: klp_shadow_get() klp_shadow_alloc() klp_shadow_get_or_alloc() klp_shadow_free() klp_shadow_free_all() that implement "shadow" variables, which allow callers to associate new shadow fields to existing data structures. This is intended to be used by livepatch modules seeking to emulate additions to data structure definitions. See Documentation/livepatch/shadow-vars.txt for a summary of the new shadow variable API, including a few common use cases. See samples/livepatch/livepatch-shadow-* for example modules that demonstrate shadow variables.
