From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> Regular krealloc() obviously can't work with managed memory. This series implements devm_krealloc() and adds the first users with hope that this helper will be adopted by other drivers currently using non-managed krealloc(). Some additional changes to the code modified by main patches are included. v1 -> v2: - remove leftover call to hwmon_device_unregister() from pmbus_core.c - add a patch extending devm_kmalloc() to handle zero size case - use WARN_ON() instead of WARN_ONCE() in devm_krealloc() when passed a pointer to non-managed memory - correctly handle the case when devm_krealloc() is passed a pointer to memory in .rodata (potentially returned by devm_kstrdup_const()) - correctly handle ZERO_SIZE_PTR passed as the ptr argument in devm_krealloc() v2 -> v3: - drop already applied patches - collect Acks - add an additional user in iio v3 -> v4: - add the kerneldoc for devm_krealloc() - WARN() outside of spinlock - rename local variable v4 -> v5: - tweak the kerneldoc Bartosz Golaszewski (3): devres: provide devm_krealloc() hwmon: pmbus: use more devres helpers iio: adc: xilinx-xadc: use devm_krealloc() .../driver-api/driver-model/devres.rst | 1 + drivers/base/devres.c | 68 +++++++++++++++++++ drivers/hwmon/pmbus/pmbus_core.c | 28 +++----- drivers/iio/adc/xilinx-xadc-core.c | 16 ++--- include/linux/device.h | 2 + 5 files changed, 88 insertions(+), 27 deletions(-) -- 2.26.1
