Why do I get errors (such as implicit mutex_lock) when I try to compile GFS?
Sometime after 2.6.15, the upstream kernel changed from using the semaphores (i_sem) within the VFS layer to using mutexes (i_mutex). If your Linux distribution is running an older kernel, you may not be able to compile GFS. Your choices are: (1) upgrade your kernel to a newer one, or (2) downgrade your GFS or change the source code so that it uses semaphores like before. Older versions are available from CVS. Because this is an open-source project, it’s constantly evolving, as does the Linux kernel. Compile problems are to be expected (and usually easily overcome) unless you are compiling against the exact same kernel the developers happen to be using at the time.
