Since I figure that there will be more people reading this kernel-doc-nano-HOWTO.txt file who are kernel developers focused on the rest of the kernel, than there will be readers of this file who are documentation developers extracting that embedded kernel-doc documentation, I have taken the liberty of making the new section added here: How to format kernel-doc comments the first section of the kernel-doc-nano-HOWTO.txt file. This first section is intended to introduce, motivate and provide basic usage of the kernel-doc mechanism for kernel hackers developing other portions of the kernel.

2008-05-26ext4: enable barriers by defaultEric Sandeen1-2/+10
I can't think of any valid reason for ext4 to not use barriers when they are available; I believe this is necessary for filesystem integrity in the face of a volatile write cache on storage. An administrator who trusts that the cache is sufficiently battery- backed (and power supplies are sufficiently redundant, etc...) can always turn it back off again. SuSE has carried such a patch for ext3 for quite some time now. Also document the mount option while we're at it.

2008-05-24fuse: fix bdi naming conflictMiklos Szeredi1-0/+4
Fuse allocates a separate bdi for each filesystem, and registers them in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for anon devices normally used by fuse, but can conflict with an already registered BDI for "fuseblk" filesystems, where sb->s_dev represents a real block device. In particularl this happens if a non-partitioned device is being mounted. Fix by registering with a different name for "fuseblk" filesystems. Thanks to Ioan Ionita for the bug report.
