Bonjour à tous
Je rencontre un problème avec mon système de fichier EXT4. Celui-ci créé des process "ext4-dio-unwrit".
Quand je regarde le fichier /fs/ext4/super.c , je vois un morceaux de code qui explique ce problème:
```c
 /*
 * The first inode we look at is the journal inode. Don't try
 * root first: it may be modified in the journal!
 */
 if (!test_opt(sb, NOLOAD) &&
 EXT4_HAS_COMPAT_FEATURE(sb, EXT4_FEATURE_COMPAT_HAS_JOURNAL)) {
 if (ext4_load_journal(sb, es, journal_devnum))
 goto failed_mount3;
 } else if (test_opt(sb, NOLOAD) && !(sb->s_flags & MS_RDONLY) &&
 EXT4_HAS_INCOMPAT_FEATURE(sb, EXT4_FEATURE_INCOMPAT_RECOVER)) {
 ext4_msg(sb, KERN_ERR, "required journal recovery "
 "suppressed and not mounted read-only");
 goto failed_mount4;
 } else {
 clear_opt(sbi->s_mount_opt, DATA_FLAGS);
 set_opt(sbi->s_mount_opt, WRITEBACK_DATA);
 sbi->s_journal = NULL;
 needs_recovery = 0;
 goto no_journal;
 }
 
```
Après une petite analyse j'en viens au fait que sb a comme valeur NOLOAD.
Problème : que veut dire NOLOAD ? 
Merci
