From 13f2e865a5766bc09ec019ffad0463d6f0f82d6d Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 21 Mar 2016 17:31:46 +0100 Subject: [PATCH] ovl: rename is_merge to is_lowest The 'is_merge' is an historical naming from when only a single lower layer could exist. With the introduction of multiple lower layers the meaning of this flag was changed to mean only the "lowest layer" (while all lower layers were being merged). So now 'is_merge' is inaccurate and hence renaming to 'is_lowest' Signed-off-by: Miklos Szeredi Orabug: 26401569 (backport upstream commit 56656e960b555cb98bc414382566dcb59aae99a2) Signed-off-by: Shan Hai Reviewed-by: Somasundaram Krishnasamy --- fs/overlayfs/readdir.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/fs/overlayfs/readdir.c b/fs/overlayfs/readdir.c index 861811d1ca59..d60897d2d8e8 100644 --- a/fs/overlayfs/readdir.c +++ b/fs/overlayfs/readdir.c @@ -37,7 +37,7 @@ struct ovl_dir_cache { struct ovl_readdir_data { struct dir_context ctx; struct dentry *dentry; - bool is_merge; + bool is_lowest; struct rb_root root; struct list_head *list; struct list_head middle; @@ -141,9 +141,9 @@ static int ovl_cache_entry_add_rb(struct ovl_readdir_data *rdd, return 0; } -static int ovl_fill_lower(struct ovl_readdir_data *rdd, - const char *name, int namelen, - loff_t offset, u64 ino, unsigned int d_type) +static int ovl_fill_lowest(struct ovl_readdir_data *rdd, + const char *name, int namelen, + loff_t offset, u64 ino, unsigned int d_type) { struct ovl_cache_entry *p; @@ -195,10 +195,10 @@ static int ovl_fill_merge(struct dir_context *ctx, const char *name, container_of(ctx, struct ovl_readdir_data, ctx); rdd->count++; - if (!rdd->is_merge) + if (!rdd->is_lowest) return ovl_cache_entry_add_rb(rdd, name, namelen, ino, d_type); else - return ovl_fill_lower(rdd, name, namelen, offset, ino, d_type); + return ovl_fill_lowest(rdd, name, namelen, offset, ino, d_type); } static int ovl_check_whiteouts(struct dentry *dir, struct ovl_readdir_data *rdd) @@ -282,7 +282,7 @@ static int ovl_dir_read_merged(struct dentry *dentry, struct list_head *list) .dentry = dentry, .list = list, .root = RB_ROOT, - .is_merge = false, + .is_lowest = false, }; int idx, next; @@ -299,7 +299,7 @@ static int ovl_dir_read_merged(struct dentry *dentry, struct list_head *list) * allows offsets to be reasonably constant */ list_add(&rdd.middle, rdd.list); - rdd.is_merge = true; + rdd.is_lowest = true; err = ovl_dir_read(&realpath, &rdd); list_del(&rdd.middle); } -- 2.50.1
