Ted, there are still endianness problems with collapse range, I kind of remember seeing some patches to fix that but I can not find those anywhere. So let me know if you have those, otherwise I'll send some. Also since this patch set (or rather the patch #5) fixes the collapse range so that it does not fail on fsx and fsstress we can drop the fallocate mode block patches I think :) Thanks! -Lukas On Wed, 16 Apr 2014, Lukas Czerner wrote: > Date: Wed, 16 Apr 2014 20:32:58 +0200 > From: Lukas Czerner <lczerner@xxxxxxxxxx> > To: linux-ext4@xxxxxxxxxxxxxxx > Cc: linkinjeon@xxxxxxxxx, Lukas Czerner <lczerner@xxxxxxxxxx> > Subject: [PATCH 1/5] ext4: Use filemap_write_and_wait_range() correctly in > collapse range > > Currently we're passing -1 as lend argumnet for > filemap_write_and_wait_range() which is wrong since lend is signed type > so it would cause some confusion and we might not write_and_wait for the > entire range we're expecting to write. > > Fix it by using LLONG_MAX instead. > > Signed-off-by: Lukas Czerner <lczerner@xxxxxxxxxx> > --- > fs/ext4/extents.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/fs/ext4/extents.c b/fs/ext4/extents.c > index ff823b7..821c1d4 100644 > --- a/fs/ext4/extents.c > +++ b/fs/ext4/extents.c > @@ -5378,7 +5378,7 @@ int ext4_collapse_range(struct inode *inode, loff_t offset, loff_t len) > punch_stop = (offset + len) >> EXT4_BLOCK_SIZE_BITS(sb); > > /* Write out all dirty pages */ > - ret = filemap_write_and_wait_range(inode->i_mapping, offset, -1); > + ret = filemap_write_and_wait_range(inode->i_mapping, offset, LLONG_MAX); > if (ret) > return ret; > > -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
