sys/sys buf.h
sys/gnu/ext2fs ext2_linux_ialloc.c fs.h
Log:
Quick fix for not being able to sync all the buffers in boot() if
an ext2fs file system is mounted. The soft update changes added
a check for B_DELWRI buffers. This exposed the complete brokenness
of the previous quick fix for failing syncs (PR 3571, committed on
1997/08/04). Use a new buffer flag B_DIRTY and don't abuse B_DELWRI.
B_DIRTY buffers are still written too late, as broken in the previous
fix. This is fairly harmless, because B_DIRTY is only used for
bitmap buffers and fsck.ext2 can fix up the bitmaps perfectly.
Fixed a race in ULCK_BUF() (bremfree() was outside of the splbio()
section).
