[ Upstream commit98c4f78dcd] In xfs_ifree, we reset the data/attr forks to extents format without bothering to free any inline data buffer that might still be around after all the blocks have been truncated off the file. Prior to commit43518812d2("xfs: remove support for inlining data/extents into the inode fork") nobody noticed because the leftover inline data after truncation was small enough to fit inside the inline buffer inside the fork itself. However, now that we've removed the inline buffer, we /always/ have to free the inline data buffer or else we leak them like crazy. This test was found by turning on kmemleak for generic/001 or generic/388. Signed-off-by: Darrick J.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
