 Modified Files:
 	src/sys/ufs/ext2fs: ext2fs_lookup.c
 
 Log Message:
 Use buffer cache, not page cache, to expand directories in ext2fs.
 
 Candidate fix for PR kern/50607, PR port-evbmips/50059.
 
 Formerly VOP_WRITE-->ext2fs_write would automatically dispatch to
 this code path for writes to directories, but I broke that in
 ext2fs_lookup.c rev. 1.78 when disentangling page-cached and
 buffer-cached writes.
 
 This was not a problem in ufs, and I didn't notice it in ext2fs,
 because ufs consistently used buffercache(9) directly instead of
 using VOP_WRITE sometimes as ext2fs did.
