I just cant belive my eyes then i saw this at the first time...
simple test: strace dd if=/dev/zero of=/mnt/file
open("/dev/zero", O_RDONLY) = 0
close(1) = 0
open("/mnt/test/file", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 1
read(0, "\0\0\0\0\0\0\0\0\0"..., 512) = 512
write(1, "\0\0\0\0\0\0\0\0"..., 512) = 512
read(0, "\0\0\0\0\0\0\0\0\0"..., 512) = 512
write(1, "\0\0\0\0\0\0\0\0"..., 512) = -1 ENOENT (No such fil
e or directory)
This strange error returned from ext4_reserve_global().
It's just typo because:
a) In fact this is 100% ENOSPC situation
b) simular function ext4_reserve_local() returns -ENOSPC
