If a dentry has a bad ino (fsck_chk_nod_blk() fails) and has a name len of 0, then __chk_dentries() will end up stuck: .... [__chk_dentries: 663] [ 4]-[0x0] name[] len[0x0] ino[0x5f1710dc] type[0xd1] [ASSERT] (sanity_check_nid: 184) --> nid is not valid. [0x5f1710dc] [__chk_dentries: 663] [ 4]-[0x0] name[] len[0x0] ino[0x5f1710dc] type[0xd1] [ASSERT] (sanity_check_nid: 184) --> nid is not valid. [0x5f1710dc] [__chk_dentries: 663] [ 4]-[0x0] name[] len[0x0] ino[0x5f1710dc] type[0xd1] [ASSERT] (sanity_check_nid: 184) --> nid is not valid. [0x5f1710dc] .... This change tries to identify bad dentries: - is the ino a valid NID? - is the FILE_TYPE a happy type?

F2FS format utilility --------------------- To use f2fs filesystem, you should format the storage partition with this utilility. Otherwise, you cannot mount f2fs. Before compilation ------------------ Your should install the following packages. - libuuid-devel or uuid-dev - pkg-config - autoconf - libtool Initial compilation ------------------- Before compilation initially, autoconf/automake tools should be run. # autoreconf --install How to compile -------------- # ./configure # make How to cross-compile (e.g., for ARM) ------------------------------------ 1. Add the below line into mkfs/Makefile.am: mkfs_f2fs_LDFLAGS = -all-static 2. Add the below line into fsck/Makefile.am: fsck_f2fs_LDFLAGS = -all-static 3. then, do: # LDFLAGS=--static ./configure \ --host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi # make How to run by default --------------------- $ ./mkfs.f2fs -l [LABEL] $DEV For more mkfs options, see man page.
