With below steps, we will see that dentry page becoming unaccessable later. This is because we forget updating i_current_depth in inode during inline dentry conversion, after that, once we failed at somewhere, it will leave i_current_depth as 0 in non-inline directory. Then, during ->lookup, the current_depth value makes all dentry pages in first level invisible. Fix it. 1) mount f2fs with inline_dentry option 2) mkdir dir 3) touch 180 files named [0-179] in dir 4) touch 180 in dir (fail after inline dir conversion) 5) ll dir ls: cannot access /mnt/f2fs/dir/0: No such file or directory ls: cannot access /mnt/f2fs/dir/1: No such file or directory ls: cannot access /mnt/f2fs/dir/2: No such file or directory ls: cannot access /mnt/f2fs/dir/3: No such file or directory ls: cannot access /mnt/f2fs/dir/4: No such file or directory drwxr-xr-x 2 root root 4096 may 13 21:47 ./ drwxr-xr-x 3 root root 4096 may 13 21:46 ../ -????????? ? ? ? ? ? 0 -????????? ? ? ? ? ? 1 -????????? ? ? ? ? ? 10 -????????? ? ? ? ? ? 100 -????????? ? ? ? ? ? 101 -????????? ? ? ? ? ? 102 Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |
