do not mark the filesystem clean, as this will mean that one or more
files were likely not completely removed (will show up as unconnected
in fsck). Prevents filesystems from being marked clean while they're
not until this problem has been figured out.
would result in a vop_inactive call for the vnode each time, resulting
in vinvalbuf->fsync. The original softdep code avoided the fsync
in vinvalbuf by not calling it if there were no dirty blocks. This
was changed in NetBSD. Also, flush_inodedeps was changed to mark
the inode as modified so that it would do an inode update and flush the
last one. This combination basically caused a sync write for each removed
file in an rm -rf (showing up delayed from the syncer a lot of the time).
If called from vinvalbuf (FSYNC_RECLAIM), and there were no dirty blocks
or pages to begin with, still do everything as normal, so that possible dirty
blocks in transit to disk are properly waited for, etc, but don't pass
UPDATE_WAIT to VOP_UPDATE, since there is no need for it in that case.
from Kirk McKusick. They implement taking pending block/inode frees
into account for the sake of correct statfs() numbers, and adding
a new softdep type (newdirblk) to correctly handle newly allocated
directory blocks.
Minor additional changes: 1) swap the newly introduced fs_pendinginodes
and fs_pendingblock fields in ffs_sb_swap, and 2) declare lkt_held
in the debug version of the softdep lock structure volatile, as it
can be modified from interrupt context #ifdef DEBUG.
was wrong, so fix it right this time. undo the previous change and
instead, replace the troublesome VOP_FSYNC()s with code that just flushes
the particular indirect blocks that we allocated. this resolves the
softdeps for those blocks. then we can change the pointer for
the first indirect block we allocated to zero, write that, and finally
invalidate all the indirect blocks we've touched. also, wait until
after we finish all this before freeing any blocks we allocated.
fixes PRs 14413 and 14423.
deal with the fragment expansion separately before the rest of the operation.
this allows us to simplify ufs_balloc_range() by not worrying about implicit
fragment expansion.
call VOP_PUTPAGES() directly for vnodes instead of
going through the UVM pager "put" vector.
