From c66e7f4e71a10e0a06d903d11acad8cc6b99c16a Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Thu, 7 Feb 2013 02:52:41 +0000 Subject: libfuse: allow disabling adaptive readdirplus This switches the -o no_readdirplus option to a tristate string: -o readdirplus=(yes|no|auto) Telling the kernel to always use readdirplus is beneficial to filesystems (e.g. GlusterFS) where the cost to perform readdir and readdirplus are identical. The default remains "auto" (if supported). --- include/fuse_kernel.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/fuse_kernel.h') diff --git a/include/fuse_kernel.h b/include/fuse_kernel.h index baee03e..4c43b44 100644 --- a/include/fuse_kernel.h +++ b/include/fuse_kernel.h @@ -218,6 +218,8 @@ struct fuse_file_lock { * FUSE_FLOCK_LOCKS: remote locking for BSD style file locks * FUSE_HAS_IOCTL_DIR: kernel supports ioctl on directories * FUSE_AUTO_INVAL_DATA: automatically invalidate cached pages + * FUSE_DO_READDIRPLUS: do READDIRPLUS (READDIR+LOOKUP in one) + * FUSE_READDIRPLUS_AUTO: adaptive readdirplus */ #define FUSE_ASYNC_READ (1 << 0) #define FUSE_POSIX_LOCKS (1 << 1) @@ -233,6 +235,7 @@ struct fuse_file_lock { #define FUSE_HAS_IOCTL_DIR (1 << 11) #define FUSE_AUTO_INVAL_DATA (1 << 12) #define FUSE_DO_READDIRPLUS (1 << 13) +#define FUSE_READDIRPLUS_AUTO (1 << 14) /** * CUSE INIT request/reply flags -- cgit v1.2.3
