From ef24f6c234de9a03aed9368163dbaad9a4f6391f Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Fri, 18 Apr 2014 10:50:23 -0400 Subject: ext4: discard preallocations after removing space Currently in ext4_collapse_range() and ext4_punch_hole() we're discarding preallocation twice. Once before we attempt to do any changes and second time after we're done with the changes. While the second call to ext4_discard_preallocations() in ext4_punch_hole() case is not needed, we need to discard preallocation right after ext4_ext_remove_space() in collapse range case because in the case we had to restart a transaction in the middle of removing space we might have new preallocations created. Remove unneeded ext4_discard_preallocations() ext4_punch_hole() and move it to the better place in ext4_collapse_range() Signed-off-by: Lukas Czerner Signed-off-by: "Theodore Ts'o" --- fs/ext4/inode.c | 1 - 1 file changed, 1 deletion(-) (limited to 'fs/ext4/inode.c') diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index b74cfd2a42ec..d7b7462a0e13 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -3621,7 +3621,6 @@ int ext4_punch_hole(struct inode *inode, loff_t offset, loff_t length) ret = ext4_free_hole_blocks(handle, inode, first_block, stop_block); - ext4_discard_preallocations(inode); up_write(&EXT4_I(inode)->i_data_sem); if (IS_SYNC(inode)) ext4_handle_sync(handle); -- cgit v1.2.3
