It's just typo because: a) In fact this is 100% ENOSPC situation b) simular function ext4_reserve_local() returns -ENOSPC Signed-off-by: Dmitriy Monakhov --- fs/ext4/balloc.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/fs/ext4/balloc.c b/fs/ext4/balloc.c index 4d7bfd2..43ae8f8 100644 --- a/fs/ext4/balloc.c +++ b/fs/ext4/balloc.c @@ -1920,7 +1920,7 @@ int ext4_reserve_global(struct super_block *sb, int blocks) { struct ext4_sb_info *sbi = EXT4_SB(sb); struct ext4_reservation_slot *rs; - int i, rc = -ENOENT; + int i, rc = -ENOSPC; __u64 free = 0; rs = sbi->s_reservation_slots; -- 1.5.2
