Ingo Molnar (3): fio: syslet.h build fix fio: allow '#' comments Jens Axboe (183): Add per-option help Complain if bad option given to 'cmdhelp' Move timeout structure where it is used Add default option values Fixup ratecycle option Reversed order of thinktime_blocks modulo operation Pretty up command help output Show allowed option values for string matching Introduce bool option type Option minval should be signed Be strict in checking option ranges Fix standard deviation calculation Merge branch 'master' of ssh://git.kernel.dk/data/git/fio strtoul() -> strtol() conversion Implement a better mean and standard deviation calculation Thread option didn't work Change timeout to runtime and rearrange option entries Change O_DIRECT vs buffered setup Change output dev= to stdev= Pretty up option looping Warn if both option variable offset and callback given Move disk utilization setup to thread itself Revert "[PATCH] Move disk utilization setup to thread itself" Really fixup disk util init Abort early for bad option given to --cmdhelp Help: thinktime is in microseconds Update irange documentation Merge branch 'master' of ssh://router/data/git/fio Cleanup some output code Update HOWTO Properly shutdown in case of serious errors Improve rate functionality Fixup rate usec cycle calculation for small values Shorten 'commitrate' to 'CR' Remove the time init check Include io depth distribution statistics The last io depth entry is actually >= 64, not > 32 Don't make file unlink the default Unlink write file if !overwrite and it exists Add support for writing aggregate bandwidth log Only generate global bandwidth log if write_bw_log set Fix typo Fix double free in sg engine error path Fix sg ioengine Add 'description' option Fix buffer alignment on non-4kb archs Rename io engines Simple support for networked IO Network engine updates Support for > 1 network connection Support residual io counts from io engines Document ->queue() in the skeleton engine Network io engine updates Network engine fixes Misc fixes Don't create files for engines that don't need them aio example should use O_DIRECT IO Remove SIGSEGV handler We should check system() return value Enable _FORTIFY_SOURCE and stack protector checking Improve dependency checking on builds Network engine cleanups and comments SG io engine: better handling of multiple files SG IO engine: remember to set io_u->file in init SG IO engine: reduce allocations and memory leaks Net engine typo CFLAGS: -fstack-protector doesn't work on older compilers Fix libaio engine SYNC libaio engine: fake work-around for sync issue Make the libaio fsync fallback really work Catch and print if directory= doesn't exist File size fix on NULL io engines Size parse should use strtoll() Random map fix More random map fixes Kill redundant header files Pretty up stat output Separate bandwidth log and rate display Fix stack overflow Allow thread/group dump regardless of error state Move td_verror() into io_ops->queue() hook Make ctrl-c work with network io and accept loop Document/comment fio.h Network engine poll() paranoia Sign warning One more round of random map fixes Total io is the sum of READ and WRITE Fix buflen trimming Add fio_assert() Woops, left debug clear in there Make the exit value meaningfull Random map needs to use ->real_file_size, not ->file_size Make fio_assert() core dump the job First cut syslet async io support Document syslet-rw engine Exabytes Let the syslet ioengine register check supportability syslet engine: use pread instead lseek+read syslet: async_head_user struct should be permanent syslet: fix leak of ring and ahu syslet: code cleanup Make fio compile on non-x86 again Defer engine ops verification check Fixup file type recognition Fixup client error exit Fix random seed for numjobs > 1 IO completion time histograms file descriptor is int Further improve child exit reaping Catch processes/threads that unexpectedly exited Don't check status if ret < 0 Add thinktime_spin parameter Change IO engine queuing Fully parallellize io_u verification Unify and fixup error handling Cleanup end IO handling Differentiate between bool error return and real error value Add support for queuing > 1 command at the time Retrieve next file to service in get_io_u() Verify requeue handling Fix busy looping for io_u_queued_complete() Clean core files on make clean Missing clear of some IO state Be safe and re-prep requeue io_u's Update documentation wrt comment Use 0 timeout for command completion peek Improve submission latency calculation Update io_u.c comments Fix sync engine completion latency First step for group reporting Add low water mark for queuing depth Leftover debug message mmap IO engine cannot extend a file Static error value checking More __must_check annotations Makefile: libdir is not used anymore Change IO latency histogram to be in power-of-10 64-bit compile warnings Fix double io_u free on error in do_verify() Don't overwrite error Correct io_u_*_complete() return checking Still need to put io_u on early exit syslet engine: style fix and ->queue() error return value fix No need to cast async_exec() syscall to void * anymore Track io_u state (free or in-flight) io_u timeout handling Include engines in dependency check Disable timeout handling for now Improve thread reap handling Thread waitpid() error check Fix crash on thread exit Further improve thread handling syslet: typo Don't check st_size for special files syslet: syscall still needs void * cast List syslet-rw as a supported option in the ioengine help dump Add more context to the error messages Correct spelling error Dump io_u on timeout Add option to select how to service multiple files Streamline thread_data data direction setting and checking Move handling of possible values into the option parser Improve rate usec calculation Rate must always calculate bytes done IO engine callback need not dump possible values Don't include engines we don't have Move completion handler into the io_u First cut at doing sequences of atoms in one commit Requeue io_u flags fix syslet v4 support Move ->commit() call to td_io_getevents() syslet engine: smart batching Speedup init_disk_util() when dealing with many jobs No need to do fadvise() on O_DIRECT/raw IO Do proper wait for pending IO on clean exit Merge branch 'master' of ssh://git.kernel.dk/data/git/fio Add iodepth_batch setting Merge branch 'master' of ssh://brick.kernel.dk/data/git/fio Extend option name from 16 to 20 bytes Move the iodepth_batch into td_io_queue() instead syslet engine: submission latency numbers Temporary iodepth_low work-around for syslets Fio version 1.12
