From f6020599aad34903d0a7e1b32181fcd719adbc44 Mon Sep 17 00:00:00 2001 From: Peter Wemm <peter@FreeBSD.org> Date: Thu, 29 Oct 1998 09:30:52 +0000 Subject: [PATCH] Use vtruncbuf() to clean out cached blocks on a file shorten rather than the more expensive vinvalbuf(), based on the FFS version of the same routine. I don't have any ext2fs filesystems to test this on. --- sys/gnu/ext2fs/ext2_inode.c | 7 ++++--- sys/gnu/fs/ext2fs/ext2_inode.c | 7 ++++--- 2 files changed, 8 insertions(+), 6 deletions(-) diff --git a/sys/gnu/ext2fs/ext2_inode.c b/sys/gnu/ext2fs/ext2_inode.c index 4699d4d51dc0..b76410b1a307 100644 --- a/sys/gnu/ext2fs/ext2_inode.c +++ b/sys/gnu/ext2fs/ext2_inode.c @@ -142,7 +142,7 @@ ext2_truncate(vp, length, flags, cred, p) register struct ext2_sb_info *fs; struct buf *bp; int offset, size, level; - long count, nblocks, vflags, blocksreleased = 0; + long count, nblocks, blocksreleased = 0; struct timeval tv; register int i; int aflags, error, allerror; @@ -268,8 +268,9 @@ printf("ext2_truncate called %d to %d\n", VTOI(ovp)->i_number, length); bcopy((caddr_t)&oip->i_db[0], (caddr_t)newblks, sizeof newblks); bcopy((caddr_t)oldblks, (caddr_t)&oip->i_db[0], sizeof oldblks); oip->i_size = osize; - vflags = ((length > 0) ?
