Hi all, This series cleans up several messes in the libxfs buffer handling code. First, we get rid of the overloaded (and in some places hidden usages) of LIBXFS_EXIT_ON_FAIL flag that is sprinkled throughout the buffer callers. Next, we rename the buffer get/read/put/write functions to match their kernel counterparts, which enables us to remove a bunch of ugly #defines. Then, we replace the open-coded uncached buffer logic in the callers with the same uncached buffer API as the kernel has. Finally, we move as many callers as we feasibly can to use the xfs_buf_(get|read) interfaces so that we don't have multiple entry points to the same functionality. For v2, move the "exit on io error" functionality directly into the callers. v3 added a set_buf_priority demacroing patch at the end. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=libxfs-refactor-buffer-funcs
