Name:kunit_kzalloc() - Just like kunit_kmalloc(), but zeroes the allocation.*@test: The test context object.*@size: The size in bytes of the desired memory.*@gfp: flags passed to underlying kmalloc().* See kzalloc() and kunit_kmalloc() for more information.

Proto:static inline void *kunit_kzalloc(struct kunit *test, size_t size, gfp_t gfp)

Type:void

Parameter:

TypeParameterName
struct kunit *test

sysctl_test_api_dointvec_null_tbl_dataTest that proc_dointvec will not try to use a NULL .data field even when the* length is non-zero.
sysctl_test_api_dointvec_table_maxlen_unsetSimilar to the previous test, we create a struct ctrl_table that has a .data* field that proc_dointvec cannot do anything with; however, this time it is* because we tell proc_dointvec that the size is 0.
sysctl_test_api_dointvec_table_len_is_zeroHere we provide a valid struct ctl_table, but we try to read and write from* it using a buffer of zero length, so it should still fail in a similar way as* before.
sysctl_test_api_dointvec_table_read_but_position_setTest that proc_dointvec refuses to read when the file position is non-zero.
sysctl_test_dointvec_read_happy_single_positiveTest that we can read a two digit number in a sufficiently size buffer.* Nothing fancy.
sysctl_test_dointvec_read_happy_single_negativeSame as previous test, just now with negative numbers.
sysctl_test_dointvec_write_happy_single_positiveTest that a simple positive write works.
sysctl_test_dointvec_write_happy_single_negativeSame as previous test, but now with negative numbers.
sysctl_test_api_dointvec_write_single_less_int_minTest that writing a value smaller than the minimum possible value is not* allowed.
sysctl_test_api_dointvec_write_single_greater_int_maxTest that writing the maximum possible value works.
