Есть тестовая прога (в аттаче).

С ядром 2.6.9 vs не компилируется (gcc 3.3, 2.95, 2.96):

$ gcc confdefs.c 
In file included from /usr/include/linux/fs.h:19,
                 from confdefs.c:78:
/usr/include/linux/prio_tree.h:22: error: syntax error before "pgoff_t"
/usr/include/linux/prio_tree.h:27: error: syntax error before "pgoff_t"

/usr/include/linux/prio_tree.h:29: error: `iter' undeclared (first use in this 
function)
/usr/include/linux/prio_tree.h:29: error: (Each undeclared identifier is 
reported only once
/usr/include/linux/prio_tree.h:29: error: for each function it appears in.)
/usr/include/linux/prio_tree.h:29: error: `root' undeclared (first use in this 
function)
/usr/include/linux/prio_tree.h:30: error: `r_index' undeclared (first use in 
this function)

На 2.4.27 собирается нормально, но там-то это как раз неактуально -- нужно 
собрать LVM2.
