perf tools: Avoid build splat for syscall numbers with uclibc

Individual search algorithms are * implemented in modules and chosen by the user. * * ARCHITECTURE * * User * +----------------+ * | finish()|<--------------(6)-----------------+ * |get_next_block()|<--------------(5)---------------+ | * | | Algorithm | | * | | +------------------------------+ * | | | init() find() destroy() | * | | +------------------------------+ * | | Core API ^ ^ ^ * | | +---------------+ (2) (4) (8) * | (1)|----->| prepare() |---+ | | * | (3)|----->| find()/next() |-----------+ | * | (7)|----->| destroy() |----------------------+ * +----------------+ +---------------+ * * (1) User configures a search by calling _prepare() specifying the * search parameters such as the pattern and algorithm name. * (2) Core requests the algorithm to allocate and initialize a search * configuration according to the specified parameters. * (3) User starts the search(es) by calling _find() or _next() to * fetch subsequent occurrences. A state variable is provided * to the algorithm to store persistent variables. * (4) Core eventually resets the search offset and forwards the find() * request to the algorithm. * (5) Algorithm calls get_next_block() provided by the user continuously * to fetch the data to be searched in block by block. * (6) Algorithm invokes finish() after the last call to get_next_block * to clean up any leftovers from get_next_block. (Optional) * (7) User destroys the configuration by calling _destroy(). * (8) Core notifies the algorithm to destroy algorithm specific * allocations. (Optional) * * USAGE * * Before a search can be performed, a configuration must be created * by calling textsearch_prepare() specifying the searching algorithm, * the pattern to look for and flags. As a flag, you can set TS_IGNORECASE * to perform case insensitive matching. But it might slow down * performance of algorithm, so you should use it at own your risk. * The returned configuration may then be used for an arbitrary * amount of times and even in parallel as long as a separate struct * ts_state variable is provided to every instance. * * The actual search is performed by either calling textsearch_find_- * continuous() for linear data or by providing an own get_next_block() * implementation and calling textsearch_find(). Both functions return * the position of the first occurrence of the pattern or UINT_MAX if * no match was found. Subsequent occurrences can be found by calling * textsearch_next() regardless of the linearity of the data. * * Once you're done using a configuration it must be given back via * textsearch_destroy. * * EXAMPLE * * int pos; * struct ts_config *conf; * struct ts_state state; * const char *pattern = "chicken"; * const char *example = "We dance the funky chicken"; * * conf = textsearch_prepare("kmp", pattern, strlen(pattern), * GFP_KERNEL, TS_AUTOLOAD); * if (IS_ERR(conf)) { * err = PTR_ERR(conf); * goto errout; * } * * pos = textsearch_find_continuous(conf, &state, example, strlen(example)); * if (pos != UINT_MAX) * panic("Oh my god, dancing chickens at %d\n", pos); * * textsearch_destroy(conf); * ========================================================================== */ #include <linux/module.h> #include <linux/types.h> #include <linux/string.h>
