Its filename was fat-kill-d_invalidate-in-vfat_lookup.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: fat: Kill d_invalidate() in vfat_lookup() From: OGAWA Hirofumi d_invalidate() for positive dentry doesn't work in some cases (vfsmount, nfsd, and maybe others). shrink_dcache_parent() by d_invalidate() is pointless for vfat usage at all. So, this kills it, and intead of it uses d_move(). To save old behavior, this returns alias simply for directory (don't change pwd, etc..). the directory lookup shouldn't be important for performance.
