Also if target returns 0 for capacity then make it ULLONG_MAX. df does not like zero-size filesystems Signed-off-by: Boaz Harrosh --- diff --git a/fs/exofs/super.c b/fs/exofs/super.c index 920f0165edf3..28add3eac0a4 100644 --- a/fs/exofs/super.c +++ b/fs/exofs/super.c @@ -473,9 +473,11 @@ static int exofs_statfs(struct dentry *dentry, struct kstatfs *buf) goto out; ret = extract_attr_from_req(or, &attrs[0]); - if (likely(!ret)) + if (likely(!ret)) { capacity = get_unaligned_be64(attrs[0].val_ptr); - else + if (unlikely(!capacity)) + capacity = ULLONG_MAX; + } else EXOFS_DBGMSG("exofs_statfs: get capacity failed.\n"); ret = extract_attr_from_req(or, &attrs[1]); @@ -487,8 +489,8 @@ static int exofs_statfs(struct dentry *dentry, struct kstatfs *buf) /* fill in the stats buffer */ buf->f_type = EXOFS_SUPER_MAGIC; buf->f_bsize = EXOFS_BLKSIZE; - buf->f_blocks = (capacity >> EXOFS_BLKSHIFT); - buf->f_bfree = ((capacity - used) >> EXOFS_BLKSHIFT); + buf->f_blocks = capacity >> 9; + buf->f_bfree = (capacity - used) >> 9; buf->f_bavail = buf->f_bfree; buf->f_files = sbi->s_numfiles; buf->f_ffree = EXOFS_MAX_ID - sbi->s_numfiles;
