Konstantin Belousov c5c1199c83 Extend the KPI to lock and unlock f_offset member of struct file. It ... now fully encapsulates all accesses to f_offset, and extends f_offset locking to other consumers that need it, in particular, to lseek() and variants of getdirentries(). Ensure that on 32bit architectures f_offset, which is 64bit quantity, always read and written under the mtxpool protection. This fixes apparently easy to trigger race when parallel lseek()s or lseek() and read/write could destroy file offset. The already broken ABI emulations, including iBCS and SysV, are not converted (yet). Tested by: pho No objections from: jhb MFC after: 3 weeks		2012-07-02 21:01:03 +00:00
