linux-toradex.git/include/linux/bsearch.h, branch Colibri_T30_LinuxImageV2.1Beta2_20140206 Linux kernel for Apalis and Colibri modules lib: Add generic binary search function to the kernel. 2011-05-19T07:25:27+00:00 Tim Abbott tabbott@ksplice.com 2011-04-14T18:00:19+00:00 1a94dc35bc5c166d89913dc01a49d27a3c21a455 There a large number hand-coded binary searches in the kernel (run "git grep search | grep binary" to find many of them). Since in my experience, hand-coding binary searches can be error-prone, it seems worth cleaning this up by providing a generic binary search function. This generic binary search implementation comes from Ksplice. It has the same basic API as the C library bsearch() function. Ksplice uses it in half a dozen places with 4 different comparison functions, and I think our code is substantially cleaner because of this.
