* fix open/umount raceAl Viro2010-10-29
| | | | | | | | | | | | | | nameidata_to_filp() drops nd->path or transfers it to opened file. In the former case it's a Bad Idea(tm) to do mnt_drop_write() on nd->path.mnt, since we might race with umount and vfsmount in question might be gone already. Fix: don't drop it, then... IOW, have nameidata_to_filp() grab nd->path in case it transfers it to file and do path_drop() in callers. After they are through with accessing nd->path...

* | | | 9p: Pass the correct end of buffer to p9dirent_readSripathi Kodi2010-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A patch was accepted recently for sending correct buffer size to p9stat_read. We need a similar patch in v9fs_dir_readdir_dotl to send correct end of buffer to p9dirent_read.

* | | | fs/9p: setrlimit fix for 9p writeHarsh Prateek Bora2010-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current 9p client file write code does not check for RLIMIT_FSIZE resource. This bug was found by running LTP test case for setrlimit. This bug is fixed by calling generic_write_checks before sending the write request to the server. Without this patch: the write function is allowed to write above the RLIMIT_FSIZE set by user. With this patch: the write function checks for RLIMIT_SIZE and writes upto the size limit.
