fvdl ce4bcf47f3 Do not call MALLOC with M_WAITOK while holding the "lock". Thanks to
Ethan Solomita for the reminder.

Mark the parent vnode lock as recursive while flushing pagedeps. XXX.
Should fix kern/10564.

jdolecek b0fb24279c change the lf_advlock() arguments from
int     lf_advlock __P((struct lockf **,
           off_t, caddr_t, int, struct flock *, int));
to

int     lf_advlock __P((struct vop_advlock_args *, struct lockf **, off_t));

This matches common usage and is also compatible with similar change
in FreeBSD (though they use u_quad_t as last arg).

jdolecek 166a3f16dd ext2fs_reload(), ext2fs_mountfs(): do devvp locking same way as ffs
this has not shown any good or bad effect, but might help narrow
some problems people seen with ext2fs reload (hi Soren!)

perseant 90b9d9b502 Clean up accounting of lfs_uinodes (dirty but unwritten inodes).
Make lfs_uinodes a signed quantity for debugging purposes, and set it to
zero as fs mount time.

Enclose setting/clearing of the dirty flags (IN_MODIFIED, IN_ACCESSED,
IN_CLEANING) in macros, and use those macros everywhere.  Make
LFS_ITIMES use these macros; updated the ITIMES macro in inode.h to know
about this.  Make ufs_getattr use ITIMES instead of FFS_ITIMES.

perseant bc303e52cb Fix errors observed while trying to fill the filesystem with yesterday's
fixes:

- Write copies of bfree and avail in the CLEANERINFO block, so the
  cleaner doesn't have to guess which superblock has the current
  information (if indeed any do).

- Tighten up accounting of lfs_avail (more needs to be done).

- When cleansing indirect blocks of UNWRITTEN, make sure not to mark
  them clean, since they'll need to be rewritten later.

mjacob eb17c77233 Add missing second argument to tablefull call. I *think* the added

been written to disk.

perseant 235a4dd595 i_lfs_effnblks fixes. Put debugging printfs under #ifdef DEBUG_LFS. 2000-07-03 08:20:58 +00:00
perseant ef2da50400 Allow the number of free segments reserved for the cleaner to be
parametrized in the filesystem, defaulting to MIN_FREE_SEGS = 2 but set
to something more reasonable at newfs_lfs time.

Note the number of blocks that have been scheduled for writing but which
are not yet on disk in an inode extension, i_lfs_effnblks.  Move
i_ffs_effnlink out of the ffs extension and onto the main inode, since
it's used all over the shared code and the lfs extension would clobber
it.

At inode write time, indirect blocks and inode-held blocks of inodes
that have i_lfs_effnblks != i_ffs_blocks are cleansed of UNWRITTEN disk
addresses, so that these never make it to disk.

fvdl fa78158b15 Rearrange code around getnewvnode as was already done for ffs, to avoid

fvdl d09958adad Due to popular demand, change vinsheadfree to ungetnewvnode to make
the name clearer. No functional change.
2000-06-27 23:51:22 +00:00
fvdl bba2403203 In ffs_vget, do not hold ufs_haslock across the call to getnewvnode.
We may sleep in it, or even recurse, with softdeps. Instead, grab
the lock later, but check if noone else has beaten us to the VFS_VGET
operation, and if so, roll back getnewvnode using vinsheadfree, and
just return.

perseant 39b86955ed Fixes associated with filling an LFS:
Change the space computation to appear to change the size of the *disk*
rather than the *bytes used* when more segment summaries and inode
blocks are written.  Try to estimate the amount of space that these will
take up when more files are written, so the disk size doesn't change too
much.

Regularize error returns from lfs_valloc, lfs_balloc, lfs_truncate: they
now fail entirely, rather than succeeding half-way and leaving the fs in
an inconsistent state.

Rewrite lfs_truncate, mostly stealing from ffs_truncate.  The old
lfs_truncate had difficulty truncating a large file to a non-zero size
(indirect blocks were not handled appropriately).

Unmark VDIROP on fvp after ufs_remove, ufs_rmdir, so these can be
reclaimed immediately: this vnode would not be written to disk again
anyway if the removal succeeded, and if it failed, no directory
operation occurred.

ufs_makeinode and ufs_mkdir now remove IN_ADIROP on error.

pk 88b0328aca We shouldn't be defining DEBUG and DIAGNOSTIC on our own; these may have
unwanted side-effects in the header files. For now, do the internal
#defines after including the headers.

perseant fd451352d9 Read i_ffs_gen from the version number in the Ifile during lfs_valloc,
instead of keeping it always == 1.  (The ifile version number is
increased on vfree.)  May address PR #7213, but I haven't been able to
test thoroughly enough to say for sure.

references (locked for VOP_INACTIVE at the end of vrele) and it's okay.
Check the return value of lfs_vref where appropriate.
Fixes PR #s 10285 and 10352.

fvdl 4f11634756 Allow MNT_SOFTDEP to be passed in via the mount(2) system call, do not
require it to be set via tunefs(8). Silently ignore it when doing
an update mount of a writeable filesystem, the FFS/softdep code isn't ready

the head of the inode free list (on the superblock) always matches the
rest of the free list (in the ifile).

Protect lfs_fragextend with seglock, to prevent the segment byte count
fudging from making its way to disk.

mycroft 64f5a574a7 In ffs_update():
* Move the clearing of IN_MODIFIED and IN_ACCESSED later, so they are not
  cleared if the bread() failed.
* Explicitly set waitfor to 0 in the softdep case, if IN_MODIFIED is not
  set (mirroring the bwrite()/bdwrite() decision).

fvdl f0112539bd Mark an inode as changed after a rename. It wasn't before in the softdep
case, which created inodes with dependencies, but no IN_* flag set,
so the dependencies were never flushed (after the waitfor check in
ffs_update was removed).

mycroft d747ada9c2 Add a new inode flags called IN_ACCESSED. This used in place of IN_MODIFIED
to record that the atime was updated.  In ffs_update(), we only do synchronous

mycroft 941524439a Never call softdep_sync_metadata() in the FSYNC_RECLAIM case. Any pending
blocks are detached from the vnode at this point.  When the dependencies are
broken to enable writing the blocks, the vnode will be regenerated.  (The only
reason we sync buffers in this case is that they have to be detached from the
vnode.)
2000-05-29 17:19:20 +00:00
mycroft c47adf55e0 In ffs_fsync(), remove the FSYNC_RECLAIM special case, so that it properly
waits for pending buffers, and doesn't throw away time stamp updates.
