[PATCH v4][next] xfs: Replace one-element arrays with flexible-array members

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

 



There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

Refactor the code according to the use of flexible-array members in
multiple structures, instead of one-element arrays. Also, make use of
the new struct_size() helper to properly calculate the size of multiple
structures that contain flexible-array members. Additionally, wrap
some calls to the struct_size() helper in multiple inline functions.

Below are the results of running xfstests for "all" with the following
configuration in local.config:

export TEST_DEV=/dev/sdb1
export TEST_DIR=/mnt/test
export SCRATCH_DEV=/dev/sdb2
export SCRATCH_MNT=/mnt/scratch

The size for both partitions /dev/sdb1 and /dev/sdb2 is 25GB.

These are the results of running ./check -g all on 5.12.0-rc6 kernel:

Changes in v4:
 - Fix size for kmem_cache_create() in fs/xfs/xfs_super.c:xfs_init_zones().
 - Update changelog text with test results on Linux 5.12-rc6.

Changes in v3:
 - Add multiple inline functions as wrappers for struct_size(), as
   per Darrick's request.
 - Use type size_t instead of uint for a couple of objects.

Changes in v2:
 - Use struct_size() helper in more places.
 - Update changelog text with testing results on Linux 5.12.0-rc2.
 - Fix issue with use of struct_size() with the right struct object.
 - Use flex_array_size() helper.
