This patch set improves symbol_search/symbol_exists performance by introducing hash table for kernel modules symbols. v2 -> v3: 1) Seperate v2 patch into multiple patches. 2) Several code indented formatting. 3) Moved "if (sp != NULL)" check from mod_symtable_hash_install/remove_range into symname_hash_install/remove, and shorten it to be "if (!sp)" check. 4) Replaced "index = index > 0 ? index : -index;" into abs() in SYMNAME_HASH_INDEX macro. 5) Replaced the code of remove hash table elements in symname_hash_remove with Kazu's version, and variable "tmp" of v2 patch get removed. 6) Removed "first_encounter" check in symname_hash_remove. 7) Add assert check in symname_hash_install. Tao Liu (4): Improve the performance of symbol searching for kernel modules Get the absolute value of SYMNAME_HASH_INDEX Set name_hash_next field to be NULL for the newly installed elements Add assert check if an element is installed one more time defs.h | 3 +- kernel.c | 1 + symbols.c | 170 +++++++++++++++++++++++++++++------------------------- 3 files changed, 95 insertions(+), 79 deletions(-) -- 2.29.2 -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/crash-utility
