[PATCH] mke2fs: Use ext2fs_flush() only once

[PATCH] mke2fs: Use ext2fs_flush() only once

[Lukas Czerner]

We are doing ext2fs_flush() twice right now at the end of the mke2fs.
First by directly calling ext2fs_flush() which is intended to write
superblock and fs accounting information. And then it is invoked again
when we are calling ext2fs_close(), only this time, because the fs is
not dirty, we are writing out only superblock.

I think it is bad to call it twice because even when writing only super
block it takes some time on bigger file systems and moreover
ext2fs_close() can fail without any reasonable explanation for the user.
Also ext2fs_flush() is printing out progress and it is confusing for the
users.

Fix all this by removing the ext2fs_flush() and leaving it all to
ext2fs_close(). However we need to introduce new variables to store
check interval and max mount count, because fs structure is freed on
ext2fs_close() and we really want to print those information as the last
info for the user.

Re: [PATCH] mke2fs: Use ext2fs_flush() only once

[Ted Ts'o]

Thanks, applied, with an obvious bugfix:

../../misc/util.c: In function ‘print_check_message’:
../../misc/util.c:291: warning: format ‘%g’ expects type ‘double’, but argument 3 has type ‘unsigned int’

the (double) cast was dropped in your patch.

The message should be made a bit better in the case that
s_max_mnt_count or s_checkinterval is zero, but that's a separate
patch.
