This also works around limitations in the ext4 block allocator, which can't allocate more than 2048 blocks at a time. So we need to defeat the round-robin characteristics of the writeback code and try to write out as many blocks in one inode before allowing the writeback code to move on to another inode. We add a a new per-filesystem tunable, max_writeback_mb_bump, which caps this to a default of 128mb per inode.

Since systemtap doesn't use TP_fast_assign(), we can use a blind structure definition and then make sure the needed header files are defined before the ext4 source files #include the trace/events/ext4.h header file. https://bugzilla.redhat.com/show_bug.cgi?id=512478 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> 2009-07-15T01:34:32+00:00 Linus Torvalds torvalds@linux-foundation.org 2009-07-15T01:34:32+00:00 urn:sha1:c0c50b541a4b147c5c2572ed051420238c47f57a * 'tracing-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: tracing/function-profiler: do not free per cpu variable stat tracing/events: Move TRACE_SYSTEM outside of include guard 2009-07-13T08:59:55+00:00 Li Zefan lizf@cn.fujitsu.com 2009-07-13T02:33:21+00:00 urn:sha1:d0b6e04a4cd8360e3c9c419f7c30a3081a0c142a If TRACE_INCLDUE_FILE is defined, <trace/events/TRACE_INCLUDE_FILE.h> will be included and compiled, otherwise it will be <trace/events/TRACE_SYSTEM.h> So TRACE_SYSTEM should be defined outside of #if proctection, just like TRACE_INCLUDE_FILE.
