Eliminate unnecessary variables.

Eliminate redundant setting of a page's valid bits and pointless clearing

of the same page's dirty bits.

Remove the thread argument from the FSD (File-System Dependent) parts of

the VFS. Now all the VFS_* functions and relating parts don't want the context as long as it always refers to curthread. In some points, in particular when dealing with VOPs and functions living in the same namespace (eg. vflush) which still need to be converted, pass curthread explicitly in order to retain the old behaviour. Such loose ends will be fixed ASAP. While here fix a bug: now, UFS_EXTATTR can be compiled alone without the UFS_EXTATTR_AUTOSTART option. VFS KPI is heavilly changed by this commit so thirdy parts modules needs to be recompiled. Bump __FreeBSD_version in order to signal such situation.

Use uiomove_fromphys() instead of the combination of sf_buf and uiomove().

This is not only shorter; it also eliminates unnecessary thread pinning on architectures that implement a direct map. MFC after: 3 weeks

The kernel implemented 'memcmp' is an alias for 'bcmp'. However, memcmp

2008-09-23T14:45:10Z

and bcmp are not the same thing. 'man bcmp' states that the return is "non-zero" if the two byte strings are not identical. Where as, 'man memcmp' states that the return is the "difference between the first two differing bytes (treated as unsigned char values" if the two byte strings are not identical. So provide a proper memcmp(9), but it is a C implementation not a tuned assembly implementation. Therefore bcmp(9) should be preferred over memcmp(9).

initialize the vattr structure in VOP_GETATTR() with VATTR_NULL(), vattr_null() or by zeroing it. Remove these to allow preinitialization of fields work in vn_stat(). This is needed to get birthtime initialized correctly. Submitted by: Jaakko Heinonen Discussed on: freebsd-fs MFC after: 1 month
