* posix: Support thread-safe vectored writes/readsShehjar Tikoo2010-05-051-84/+90
| | | | | | | | | | | | | | | | | | | | | | | | ..by maintaining internal offsets and using pwrite/pread instead of writev/read. The recent io-threads change is causing concurrent writes to a file from different io-threads. This results in a race between two threads both of which are trying to call lseek-writev. The lseek-writev sequence should be a critical section. This is where pwrite syscall helps. pwrite also requires an offset to be given so for supporting pwrites for multiple iovecs we maintain an offset within posix for the duration of the write fop and pass this internal offset to pwrite. The same logic also applies to read, only difference is that we do not need to read multiple iovecs but only provide an atomic lseek-read sequence.

| | | | | | | | | | | | | | | | | | | Submitted-by: Krishna Srinivas <krishna@gluster.com> NOTE: fixed compilation issues in posix.c introduced while merging storage/posix polls for FS/kernel being functional by issuing statvfs() call. In case statvfs expires the timer, storage/posix will send CHILD_DOWN to upper translator. Ultimately this will cause protocol/server to disconnect all clients connected and also cleans up the data structures. Hence if soft lockup or other kernel bug causes backend FS to hang, the clients will not be hung. Signed-off-by: Krishna Srinivas <krishna@gluster.com> Signed-off-by: Anand V.
