Hello,
I'm newbie in kernel programming and try to write filesystem, and have two problems.
1) There are not "<mount-point>/.", "<mount-point>/..", and "<mount-point>/<any_dir>/.." entries, for example: # ls -a dir link text_file # ls -a dir/ . level_2 # ls -a dir/level_2/ . ..
I make filldir(dirent, ".", 1, i, ino, DT_DIR) and filldir(dirent, "..", 2, i, parent_ino(filp->f_dentry)) in readdir() for all directories.
2) Problem with removing not empty directories: # ls -l total 135 drwxr-xr-x 3 root root 0 Nov 6 17:48 dir lr-xr-xr-x 1 root root 1024 Nov 2 11:13 link -> /home/undefer -r-xr-xr-x 1 root root 274944 Nov 2 11:13 text_file
# rmdir dir rmdir: `dir': Directory not empty
# ls -l total 135 ?--------- 0 root root 0 Jan 1 1970 dir lr-xr-xr-x 1 root root 1024 Nov 2 11:13 link -> /home/undefer -r-xr-xr-x 1 root root 274944 Nov 2 11:13 text_file So anything call "delete_inode" for directory and it's entries but it is not empty! What is? Why? What I could made not so?
Thanks, Sorry for bad english.
