+
+The following mount options are supported:
+(*) == default
+
+iocharset=name Character set to use for converting from Unicode to
+ ASCII. The default is to do no conversion. Use
+ iocharset=utf8 for UTF-8 translations. This requires
+ CONFIG_NLS_UTF8 to be set in the kernel .config file.
+ iocharset=none specifies the default behavior explicitly.
+
+resize=value Resize the volume to <value> blocks. JFS only supports
+ growing a volume, not shrinking it. This option is only
+ valid during a remount, when the volume is mounted
+ read-write. The resize keyword with no value will grow
+ the volume to the full size of the partition.
+
+nointegrity Do not write to the journal. The primary use of this option
+ is to allow for higher performance when restoring a volume
+ from backup media. The integrity of the volume is not
+ guaranteed if the system abnormally abends.
+
+integrity(*) Commit metadata changes to the journal. Use this option to
+ remount a volume where the nointegrity option was
+ previously specified in order to restore normal behavior.
+
+errors=continue Keep going on a filesystem error.
+errors=remount-ro(*) Remount the filesystem read-only on an error.
+errors=panic Panic and halt the machine if an error occurs.
+
+uid=value Override on-disk uid with specified value
+gid=value Override on-disk gid with specified value
+umask=value Override on-disk umask with specified octal value. For
+ directories, the execute bit will be set if the corresponding
+ read bit is set.
+
+discard=minlen This enables/disables the use of discard/TRIM commands.
+discard The discard/TRIM commands are sent to the underlying
+nodiscard(*) block device when blocks are freed. This is useful for SSD
+ devices and sparse/thinly-provisioned LUNs. The FITRIM ioctl
+ command is also available together with the nodiscard option.
+ The value of minlen specifies the minimum blockcount, when
+ a TRIM command to the block device is considered useful.
+ When no value is given to the discard option, it defaults to
+ 64 blocks, which means 256KiB in JFS.
+ The minlen value of discard overrides the minlen value given
+ on an FITRIM ioctl().
