https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233578 --- Comment #4 from Ed Schouten <ed@FreeBSD.org> --- Hi there, Instead of going down this road, what are your thoughts on the following? - Tossing out the use of O_EXLOCK entirely and leave the file writing as it is now, - Using a single lock file acquisition in pututxline() to serialise write access all data files in one go. This likely makes the code a bit simpler/lighter, while also improving the sequential consistency guarantees between the data files. -- You are receiving this mail because: You are the assignee for the bug.help
