[PATCH-next 0/4] RDMA: sprintf to sysfs_emit conversions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A recent commit added a sysfs_emit and sysfs_emit_at to allow various
sysfs show functions to ensure that the PAGE_SIZE buffer argument is
never overrun and always NUL terminated.

Convert the RDMA/InfiniBand subsystem to use these new functions.

The first 2 patches exclusively used coccinelle to convert uses.
The third and fourth patches were done manually.

Compiled allyesconfig and defconfig with all infiniband options selected
no warnings, but untested, no hardward

Overall object size is reduced

total size: allyesconfig x86-64

Joe Perches (4):
  RDMA: Convert sysfs device * show functions to use sysfs_emit()
  RDMA: Convert sysfs kobject * show functions to use sysfs_emit()
  RDMA: manual changes for sysfs_emit and neatening
  RDMA: Convert various random sprintf sysfs _show uses to sysfs_emit
