2005-05-28Disable the recently enabled optimization since it seems to cause aArtur Grabowski
loop in the kernel that makes us overwrite the stack and anything else we might run into. beck@ pedro@ ok
2005-05-28ufs_whiteout() is now pointless, remove it, okay millert@Pedro Martelletto

2005-04-30Add support for large files (> 4GB).Niall O'Higgins
Automatically converts old filesystems to use this if they are already at revision 1 (like Linux). Revision 0 filesystems don't get converted (unlike Linux). From NetBSD
2005-04-23pay attention to failed relookups, compensate for a reference lost inPedro Martelletto
ufs_checkpath(), optimize a if/else's logical structure. diff mostly from netbsd, okay tedu@ fgsch@ deraadt@, tested by many, jcs@ in particular, thanks. fixes PRs 4040, 4126, 4169 and 4180.
2005-03-06Use V_SAVE instead of hardcoding it, no binary change.Pedro Martelletto
2005-03-01Avoid 32-bit overflow by casting blk arg to lblktosize() to (off_t). SolvesAaron Campbell
performance loss issue in some cases when reading past the 2GB boundary in large files. Testing by drahn@, otto@, danh@, krw@, tom@, jaredy@. From FreeBSD. tedu@, pedro@ ok.
2005-02-17miscellaneous typo fixes:Jean-Francois Brousseau
- sturct -> struct (spotted by pedro) - elimination of consecutive 'the' words ok jmc@, henning@, krw@, robert@, some whining by jolan@
2005-02-17Remove dead code that has moved to ufs_vfsops.c long ago.Pedro Martelletto
2004-12-26Use list and queue macros where applicable to make the code easier to read;Miod Vallat
no change in compiler assembly output.
2004-12-09When removing the last item from a non-empty worklist, the worklistTodd C. Miller
tail pointer must be updated; from FreeBSD (mckusick). Appears to fix problems I was seeing with processes stuck with WCHAN=inode in rev 1.50. OK pedro@ and tedu@.
2004-12-08Move a FREE_LOCK until after a potential continue so we don't tryTodd C. Miller
to free the lock twice. Doesn't actually make any difference for us (no .o file diff) since the code block that contains the continue is currently commented out but it makes sense to fix this now so if/when that code is enabled we don't get bitten. From FreeBSD, ok pedro@.

'looks fine' millert@, krw@. ok jmc@
2004-11-06disable changing softdep linkcnt (last commit). it can cause a loop thatTed Unangst
locks the vnode twice, and we can't fix it right now. discussed with pedro.

ok marius@ tedu@
2004-10-10inform softdep of inode mode change, from freebsd. while i'm at it,Pedro Martelletto
check for ufs_truncate failure and do a bit of the usual null for pointers, spacing stuff. ok tedu@

2004-08-12Prevent a panic by validating the super block size as recorded in theOtto Moerbeek
superblock; make the block size check also catch negative values. ok miller@ tedu@
2004-07-25more consistent handling of vnode recount during rename.Ted Unangst
should solve some panics. various testing for a while.
2004-07-21I was wrong. The assymetry created by the proc argument to rw_enter_writeArtur Grabowski
is horrible and doesn't add anything. Remove it. XXX - the fdplock macro will need a separate cleanup. niklas@ markus@ ok
2004-07-14trailing '\n' in printf, ok deraadt@Pedro Martelletto
2004-07-13Change mode_t and nlink_t from 16bit to 32bit. This allows us toTodd C. Miller
use mode_t in syscalls.master and to use mode_t in more places in the kernel. It also makes lint much more useful on kernel code. I've also added a placeholder for st_birthtime to make a UFS2 import easier at some future date. Requested by and OK deraadt@

2004-06-24This moves access to wall and uptime variables in MI code,Thorsten Lockert
encapsulating all such access into wall-defined functions that makes sure locking is done as needed. It also cleans up some uses of wall time vs. uptime some places, but there is sure to be more of these needed as well, particularily in MD code. Also, many current calls to microtime() should probably be changed to getmicrotime(), or to the {,get}microuptime() versions. ok art@ deraadt@ aaron@ matthieu@ beck@ sturm@ millert@ others "Oh, that is not your problem!" from miod@
2004-06-21First step towards more sane time handling in the kernel -- this changesThorsten Lockert
things such that code that only need a second-resolution uptime or wall time, and used to get that from time.tv_secs or mono_time.tv_secs now get this from separate time_t globals time_second and time_uptime. ok art@ niklas@ nordin@

2003-12-28add ian dowse's dirhash code from freebsd.Ted Unangst
by building a hash table for large directories, lookups and deletions become about constant time. this is an excellent improvement for dirs with 10k or more files. some more cleanup to come, but the code works. enabled with option UFS_DIRHASH testing brad millert otto
